Fixing issues with ConfigMgr client log collection

In ConfigMgr version 2002 Microsoft introduced the ability to remotely collect client logs using the client notification channel and have them delivered to your Management point. This is very useful as it means you can troubleshoot client issues without disturbing your users.

Assuming that the connection between your Management point and your client(s) is healthy and the request is making it to the client, a new log will appear in C:\Windows\CCM\Logs called Diagnostic.log when the log collection is initiated. A successful log collection will generate three lines in the log:

Collecting log files ...
PowerShell path: C:\WINDOWS\system32\WindowsPowerShell\v1.0\PowerShell.exe
FileCollection: Successfully sent report. Destination:mp:MP_SinvCollFileEndpoint, ID: {F4266B5E-BA06-46B3-91ED-B5C03539043E}, Timeout: 10080 minutes MsgMode: Signed, Not Encrypted

Note that this is when verbose logging disabled.

In a rare case, however, client log collection may not work. One reason may be that the size of the compressed client logs exceeds 100 MB, which is the limit according to Microsoft’s documentation. Another reason, which is not documented anywhere, is that if the full path of any log (including the log name itself) exceeds 116 characters in length, the log collection will fail.

For example, the following would work as the full path is exactly 116 characters:


However, the following log would cause an error as the full path is longer than 116 characters:


If you attempt to collect client logs from a client that has log files that exceed the 116-character path limit, you will see the following errors in Diagnostics.log:

GetAllCcmLogs: Non-zero exit code. 1.
GetAllCcmLogs: Failed. 0x80004005.

This is very unlikely to cause you a problem as none of the ConfigMgr client log files are this long. However, if you capture application install\uninstall logs and decided to put them in the same folder as the ConfigMgr client logs directory, there is a possibility that they will exceed this path length. If this is the case, you will need to choose a new path to store these logs and move them on all your clients.

Enabling HSTS and selecting most secure ciphers and protocols for HTTPS for ConfigMgr

Many IT security departments these days frequently scan their servers using a vulnerability scanner such as Nessus or Qualys to look for software that needs patching or settings that need to be changed, in the hopes of finding and fixing them before the bad guys exploit them. On web servers, the findings may include needing to enable HSTS (HTTP Strict Transport Security) and configuring the server to only use the latest versions of TLS and use the most secure ciphers. As many ConfigMgr roles rely on a web server, this may mean your ConfigMgr server(s) appears on the vulnerability report with findings.

So, the big question is: Does enabling HSTS cause problems for ConfigMgr? I have tested this extensively and I believe the answer is no, it does not cause problems. If you are concerned, there is a way to minimise the risk by settings the “max-age” for HTST to just 1 hour to begin with (in the end you should set this to 1 year as that is the industry recommended time).

The second question is: Does ConfigMgr still work if you limit the TLS protocols and ciphers to only the most secure? Again, the answer is yes, ConfigMgr continues to work just fine.

Before you begin, you must understand what HSTS is and how it could break things if it is set incorrectly. HSTS instructs browsers to always expect a secure connection to a site and they will refuse to connect in the future if they do not find a valid SSL certificate. Due to this you must only set HSTS if you are running ConfigMgr with SSL certificates and can guarantee that you will always be doing so in the future.

To enable HSTS you must be running all ConfigMgr roles in HTTPS mode. This includes the Management point and Distribution point, as well as the Enrollment point and Enrollment proxy point if you are still using those.

WSUS must also be configured to use HTTPS.

If you are running a Reporting services point, you must use Report Server Configuration Manager to configure SQL Server Reporting Services (SSRS) to use SSL. There is also a separate process to enable HSTS on SSRS if you are using the 2019 version.

You should be aware that this guide will set HSTS for all websites hosted on your server. If you run any other sites on your ConfigMgr server, you should make sure that you can guarantee HTTPS connections to those sites as well.

Configuring HSTS in IIS 10.0
Microsoft has confusingly continued to use version 10.0 for IIS in Windows Server 2016 and 2019 even though they have added features to IIS in the newer versions of Windows Server. In Windows Server 2016 the full version for IIS is IIS 10.0 version 1607 and in Windows Server 2019 it is IIS 10.0 version 1809. HSTS can be enabled in both versions but have slightly different procedures.

If you are running Windows Server 2016, open Internet Information Services (IIS) Manager and select the site your ConfigMgr roles are running from (by default this will be Default Web Site). Double click on HTTP Response Headers, then click Add from the Actions pane on the left. In the Name field enter “Strict-Transport-Security”, and in the Value field enter “max-age=31536000; includeSubDomains”. Click OK to save this header.

Setting the Strict-Transport-Security header in IIS 10.0 on Windows Server 2016

If you are running Windows Server 2019, open Internet Information Services (IIS) Manager and select the site your ConfigMgr roles are running from (by default this will be Default Web Site). In the Actions pane on the left click HSTS… and tick Enable, put the value 31536000 in the Max-Age field and tick includeSubDomains and Redirect Http to Https. Click OK to save this setting.

Enabling HSTS in IIS 10.0 on Windows Server 2019

Note: The 31536000 value for max-age is equal to 1 year in seconds. This is the industry standard time for this value. If you want to test this before fully committing to a year you can set this value to 3600 (1 hour) or 86400 (1 day). Once you have completed your testing and are satisfied that HSTS is not causing any problems, you should set this to 31536000.

If you are running a previous version of IIS, you may still be able to enable HSTS by configuring the HTTP Response Header. Microsoft has an article that covers enabling HSTS in previous versions of IIS here.

Configuring HSTS in SQL Server Reporting Services
SQL Server Reporting Services (SSRS) has long been decoupled from IIS, so configuring HSTS for your IIS sites will not configure it for the reporting services site if you have a Reporting services point set up in ConfigMgr. In order to configure HSTS for SSRS you must be running SQL Server 2019 Reporting Services or later, as this is the first version where Microsoft has officially supported setting custom response headers.

To configure the Strict-Transport-Security header in SSRS 2019, start by opening SQL Server Management Studio and selecting Reporting Services from the Server type drop down menu and entering the server’s name, followed by the authentication details you use. Once connected, right click on the server’s name in Object Explorer on the left and select Properties. Go to Advanced and look for the CustomHeaders field. By default, this is empty, so you should enter the following value:

<CustomHeaders><Header><Name>Strict-Transport-Security</Name><Pattern>(.+)\/Reports\/(.+)</Pattern><Value>max-age=31536000; includeSubDomains=true</Value></Header></CustomHeaders>
Showing where to set the Strict-Transport-Security header in SQL Server Management Studio

This sets the header name (Strict-Transport-Security) and the value (max-age=31536000; includeSubDomains=true). You also have to use a regular expression to set which URLs will be matched and this header applied to. For a default install of SSRS, your ConfigMgr reports will be accessible at https://< If this is the case, the regex “(.+)\/Reports\/(.+)” will work as this matches any URL that has characters before and after “/Reports/”. If you need to modify this regex for your environment, I recommend using a regex testing site such as this one.

Once you have entered the text in the CustomHeaders field click OK to close the Server Properties page. You must then restart the SQL Server Reporting Services service before it will take effect.

Configuring best practise for TLS versions and cipher suites offered by IIS
The easiest way to disable old TLS versions and insecure cipher suites is to download the tool IIS Crypto from Nartac Software. Once downloaded, run it on your ConfigMgr server and click the Best Practices button at the bottom of the window. This will leave only TLS 1.0, 1.1 and 1.2 enabled and disable many less secure ciphers such as MD5 and 3DES. I would also recommend unticking TLS 1.0 to disable that.

You can review exactly what has been disabled by going through the list of protocols and ciphers that have been left enabled in the Schannel tab and the Cipher Suites tab. If you’re happy with the changes that it will make, click Apply and then close IIS Crypto. You must restart the server before the changes will take effect.

Once you have completed this you can ask your security team to rescan your ConfigMgr server and check that it no longer shows vulnerabilities relating to HSTS or insecure HTTPS protocols and cipher suites.

One way to fix error 0x87d00231 in ClientIDManagerStartup.log

If you administer ConfigMgr frequently you have probably come across your fair share of clients that are not appearing in the console, or don’t appear to be completing their registration process. The first place most of us go is the ClientIDManagerStartup.log file as this log details the CcmExec process start up and is one of the first log files that errors will show up in if there are problems communicating with the site server.

You may see the following error appear in the log file: 0x87d00231.

Unfortunately, 0x87d00231 is a fairly generic error message that pretty much just means “something went wrong”. If you Google it, you will see a variety of solutions ranging from reinstalling the client to checking your PKI environment is functioning correctly or checking the health of your Management Point(s). These are very valid suggestions; however, they could lead you down a time-consuming rabbit hole. Before you go down that rabbit hole there is one very simple thing it could be, and the answer can be quickly found in the CcmMessaging.log file:

Request to cannot be fulfilled since use of metered network is not allowed.

Yes, it could be as simple as the user of the device having set their connection as a metered connection. This can be done on Windows 8.1 and Windows 10 clients. Now you know the reason the user’s device isn’t completing its registration, you can find out why they are using a metered connection and correct it if it’s in error.

The mystery of the invisible System Center Configuration Manager update

Since mid-December 2019 I have been trying to update my SCCM lab environment from 1906 to 1910. For the first few weeks of release it was in the early update ring, but no matter how many times I ran the PowerShell script to enable early updating, the update would not appear in the Updates and Servicing node in SCCM.

Oh well, no matter, I thought. Perhaps it’s buggy and has been pulled, or maybe there’s just some odd reason my environment isn’t compatible. I’ll just wait for the general release.

General release comes and goes… and still no update. What’s going on?! I am 100% certain that my Service connection point is set to Online, I have restarted the SMS_EXECUTIVE service so many times, and also restarted the whole server just to be as thorough as possible! I know my server has internet connectivity because the Software update point is happily downloading and applying the January 2020 updates to my servers and clients. And finally, I have checked dmpdownloader.log, CMUpdate.log and hman.log and there are no obvious errors in there to tell me why I’m not seeing the latest update.

(Okay – that paragraph was a overblown way to tell you what you should definitely check if you haven’t already, before you continue to read).

So, what was going on?

Delving a little deeper in the hman.log file, I did find the following two errors:

CServerStatusReporter::DeliverToStatusManager(): ERROR: Cannot deliver status message to SMS_STATUS_MANAGER, could not write the message to varfile E:\Program Files\Microsoft Configuration Manager\inboxes\\statmsgs\90sna58w.SVF due to a file error: The file or directory is corrupted and unreadable.

Error: Failed to move file E:\Program Files\Microsoft Configuration Manager\inboxes\\ForwardingMsg\___CABConfigMgr.Update.Manifest.MCM to E:\Program Files\Microsoft Configuration Manager\inboxes\\CFD\ConfigMgr.Update.Manifest.CAB, Win32 error = 1392

When I attempted to navigate to “E:\Program Files\Microsoft Configuration Manager\inboxes\\statmsgs” I got an error message telling me the location was corrupted and unreadable!

Oops – my screenshot shows statmsgs.old. That’s because I already fixed it before posting this article.

I got the same error when I tried to navigate to “E:\Program Files\Microsoft Configuration Manager\inboxes\\CFD”. I’m not entirely certain how these two locations became corrupted, but thankfully Windows Explorer allowed me to rename them to “statmsgs.old” and “CFD.old” respectively, and then re-create the folders.

Once I restarted the SMS_EXECUTIVE service once more, hman.log finally filled up with information about the new update and the download proceeded. Finally, I have my update!

In all seriousness, this may be a very marginal case and may not be the reason you can’t see the latest update for SCCM. However, it seemed worth documenting; just in case someone else has the same symptom!

I would suggest clicking Check for updates in the Updates and Servicing node and then paying close attention to your hman.log file for any errors similar to the ones I found. Bear in mind that it might be different folders that cause errors for you, so keep an eye out for any errors with files being moved between inboxes.

Anyway, I’m off to go play with new SCCM features…!

BITS throttling causing slow SCCM client install and policy download

SCCM extensively uses Background Intelligent Transfer Service (BITS) to transfer data between a client and the SCCM server. This also affects downloading client policy! One of the first things that SCCM uses BITS for is to download the client to the machine when you initiate a client push. If BITS is heavily throttled you may find the following entries in your ccmsetup.log file (typically found in C:\Windows\ccmsetup):

Starting BITS download for client deployment files.
Download update: Copy job has been queued.
Download update: Copy job has been queued.
Download update: Copy job has been queued.

There may be some entries showing the progress of the client download, however if BITS is throttled this may be proceeding very slowly.

If you want to check whether BITS is being throttled on a particular machine open a command prompt window and type RSoP to perform a Resultant Set of Policy. Once the RSoP window opens navigate to Computer Configuration —> Administrative Template —> Network —> Background Intelligent Transfer Service (BITS) —> Limit the maximum network bandwidth for BITS background transfers and check if it is enabled and what limitations are in place.

In my case it was limited to 10 KBs at all times! Far too slow to get anything done in a reasonable time.

The next thing you can do before you start talking with your fellow sysadmins and the  network team about removing the throttling is to prove that it is the BITS throttling causing the issue. As long as you are a local administrator on one of the clients this can be done quickly by editing one registry key and restarting the Background Intelligent Transfer Service. Open regedit and navigate to HKLM\SOFTWARE\Policies\Microsoft\Windows\BITS and change EnableBitsMaxBandwidth from 1 to 0. Then open services.msc and restart Background Intelligent Transfer Service. This will remove the BITS throttling on that machine until group policy is reapplied and sets EnableBitsMaxBandwidth back to 1. Before that happens however you should have time to re-deploy the SCCM agent or push a new client policy and observe whether or not it happens in a much more timely fashion than it did before.

Error 80070057 when attempting to update Windows Server 2012 R2

Once when I was updating some servers running the version of Windows Server 2012 R2 I encountered something odd; no patches appeared in Software Center or in the Windows Update panel, even though the server was several years out of date and definitely had applicable updates!

In WindowsUpdate.log I found the following error message repeating:


The fix for this is to manually download and install KB2919355, which is the April 2014 update rollup for Windows Server 2012 R2. After this has been installed and the server has restarted, re-run your updates scan and updates will show up in Windows Update or Software Center.

Increasing the maximum run time for Windows 10 and Windows Server 2016 cumulative updates

One of the things I have noticed since starting to deploy Windows Server 2016 is that the cumulative updates can fail to install when deployed from SCCM. It starts to run but then times out due to the maximum run time having been reached. By default this is set to 10 minutes. However due to the updates being larger and taking longer to install than updates prior to the cumulative updates era 10 minutes doesn’t seem to be long enough. The fix for this is to simply increase the maximum run time for cumulative updates for both Windows Server 2016 and Windows 10 from 10 minutes to 30 minutes.

This is a bit tedious as you’ll have to do it every month for both Windows Server 2016 and every version of Windows 10 you have in your environment. Hopefully Microsoft soon catches on to this and changes the default run time to 30 minutes so that this ceases to be an issue. There is already a Configuration Manager UserVoice entry for this idea, so if you’re reading this, pop over and vote to increase its visibility!

Automatically enable BitLocker and set a PIN during an SCCM Task Sequence

Getting your operating system deployment one step closer to being zero touch is always a good goal, so with that in mind here is how to automatically enable BitLocker during OSD using a PIN that you define in a variable at the beginning of the Task Sequence.

The first thing to do is add the OSDBitlockerPIN variable to the collection you advertise your OSD Task Sequences too. This is very likely the All Unknown Computers collection. Right click on it and select Properties. Navigate to the Collection Variable tab and click New. The name is OSDBitlockerPIN and you should untick “Do not display this value in the Configuration Manager console”.


Next up open your Task Sequence and add the Enable BitLocker step. This can be placed anywhere after the Setup Windows and ConfigMgr step.1 Make sure Current operating system drive is selected and then select TPM and PIN. You can then enter anything into this field as it will be overwritten by what you enter into the OSDBitlockerPIN variable when you start the Task Sequence.


Finally, go ahead boot your client into the WinPE environment. Select your Task Sequence and click next and you will be presented with the Edit Task Sequence Variables step. You may already use the OSDComputerName variable in which case you will already be familiar with this! Double click on OSDBitlockerPIN and enter the PIN you wish to use for this machine.


Click Next and the Task Sequence will run and complete. BitLocker will be enabled and the PIN will be set. Now you don’t have to configure BitLocker after the operating system has been deployed!

1I would add the Enable BitLocker step at the very end of your Task Sequence, otherwise you will have to enter the PIN each time the machine reboots after applications or updates are installed. You could suspend BitLocker before each reboot, but why go to the extra effort.
