have you verified that the cert in your dp is updated also ? see step 5 here

In our SCCM environment we use HTTPS only for communication. Two weeks ago I replaced our existing certificate for our IIS server with a new since the existing one was set to expire on 3/2. On Monday clients started getting the following error message when trying to PXE for an image: (See 1st image, I have removed the IP address information). When I looked at the SMSPXE.LOG I found the following: (See 2nd image) When I looked at the SMSPXE.LOG I found the following: I have verified that the HTTPS bindings for the default website is using the correct certificate and that certificate does not expire till 2026. The certificate was replaced before the old one was set to expire. I also did a NETSH HTTP SHOW SSLCERT IPPORT=0.0.0.0:443 and verified that the certificate hash matched the certificate thumbprint of the SSL certificate in the site binding. I have removed the old certificate and restarted the server but clients are still getting that error message and the same WINHTTP_CALLBACK_STATUS error message is still the same. I have spent the last two days reviewing different articles and suggestions regarding this error and I am not sure how to proceed. I would be very grateful for any suggestions. Thanks!

5 years later and this bug is still alive. I am on Version 2309, and I still had to use the tip above to get the task sequence to display. So, the 2012 thing can be put to bed, it's still a bug

ah great to hear it and thanks @Cerberus24 for posting your findings, i'm sure it'll help someone !

@anyweb, thank you for your availability and troubleshooting. I have figured out the problem. The issue stemmed from the fact that I was primarily working with headless computers in my environment. Even though I was running MSTSC with the /admin or /console switch, I never properly checked if the established session was, in fact, a console session. This is why the policy would fail, and we would see errors in the logs when the policy attempted to launch the MBAM UI. I didn’t realize this until I revisited my VMs and accessed them through the console, instead of connecting via MSTSC. On existing, imaged devices, I was able to resolve the issue by manually interacting with a few devices using SCCM's remote control viewer, which establishes a console session. After logging in via SCCM’s remote viewer, the BitLocker policy executed and encrypted the drives without any issues. For anyone else in your community facing a similar problem, I addressed the headless computer issue by creating a task sequence during OS deployment. This ensures that devices are imaged with the appropriate BitLocker settings that align with my BitLocker policy. This way, all imaged devices are compliant from the start, and SCCM can still report compliance for these devices, since the policy settings are consistent and encryption is not required. Since I will mostly be accessing the headless computers via MSTSC, this solution works well for my environment.

OK, I have added the domain to hosts file and it started working. So, finally, so far so good. Now the hard part - to replicate the issue from prod ConfigMgr environment, where driver updates from Lenovo catalog do not install at all on devices. The driver updates on HP install with no issue though. 😐

Hi Niall, I can ping from host to the laptop and other way successfully. I can ping from/to DC and CM VMs to the laptop, using the 192.168 IPs. The VMs have additionally the 10. addressing with private switch. When trying to join the domain I get an error: An ADDS for the domain corp.contoso.com could not be contacted.

Be aware that if you install WDS on the 😄 drive, then want to move it to another drive, the smspxe.dll file will remain registered on the 😄 drive. RemoteInstall will not have a folder called SMSBoot. I had a server where Config Mgr had been deployed to the 😄 drive but was supposed to be on E:. The roles were removed and "NO_SMS_ON_DRIVE.SMS" was put onto the 😄 drive then Config Mgr was redeployed. There did not seem to be a way to get WDS to install and put SMSBoot into the RemoteInstall folder. Digging around in the registry I found entries for it on the 😄 drive and edited them to point to the E: drive (HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WDSServer\Providers\WDSPXE\Providers\SMSPXE). This resolved the issue. I suspect it will help those who are looking for a solution for an empty SMSBoot folder, too.

hi @Martinez in my #11 lab (domain controller) I have a DHCP server running, so any device that connects into that lab will receive a valid ip address I hope that helps cheers niall

Hi Niall, As always, great guide! I am trying this on a laptop with the MECM lab from Microsoft [Windows 11 and Office 365 Deployment Lab Kit]. I have connected the lab and client device the same way. How did you address the devices, same subnet 198.162 on both as on the screenshot and type external, right?

Introduction Panu Sakku posted the following tweet recently asking if anyone noticed their CMG (Cloud Management Gateway) was broken after it got a recent update. I checked my lab, and sure enough, it was also dead in the water, and could not start. After checking the logs I replied to Panu. The errors in the SMS_CLOUD_PROXYCONNECTOR.log file in red were many, and here’s a paste of some of them to help others find out how to resolve this problem.

But let’s see why he did that. If you go to the Azure portal and locate your CMG, you’ll see it’s got a Failed status (1). If you click Restart (2) after a few minutes it’ll be failed again but you’ll get a notification (3) explaining what failed. Failed to restart virtual machine scale set Failed to restart virtual machine scale set ‘cloudattachcmg’. Error: VM has reported a user failure when processing extension ‘InstallCMG’. Please correct the error and try again. (publisher ‘Microsoft.Compute’ and type ‘CustomScriptExtension’). Error code: ‘2’. Error message: ‘Command execution finished, but failed because it returned a non-zero exit code of: ‘1”. Detailed error: ”. More information on troubleshooting is available at https://aka.ms/VMExtensionCSEWindowsTroubleshoot. So it’s clear that Azure has problems starting the CMG due to “VM has reported a user failure when processing extension ‘InstallCMG’.” I wonder what the ‘user failure’ means ? Let’s try Johnny’s advice then. Fixing the problem ? Click on Settings, select Extensions + applications and then place a checkmark in InstallCMG, it’ll bring up it’s properties and you can now select Uninstall. The settings in that extension are listed here, just to see if they change after the fix. “commandToExecute”: “powershell.exe -File cmgsetup.ps1 -storageAccountName cloudattachcmg -storageEndpointSuffix core.windows.net -serviceName cloudattachcmg -serviceCName cloudattachcmg.azurenoob.com -certStoreName My -certThumbprint 2D2F89A0F44335C0D57678DA5AC80663660B0250 -crlAction enable -tls12Enforced True -nodeName localhost -bDisabledSharedKey True”, “fileUris”: [ “https://cloudattachcmg.blob.core.windows.net/stageartifacts/cmgsetup.ps1” ] } After a while it’ll be uninstalled and you’ll get a notification telling you that it’s done. After changing Client revocation settings, and changing the maintenance window to be in the future (otherwise you’ll get an error) before clicking Apply. A quick look at the CloudMgr.log reveals it’s updating the CMG and the status of the CMG in SCCM changes to Upgrading. while in Azure, the CMG has a status of Updating. and after a while everything should hopefully be fixed. Note: If it works for you, then don’t forget to set the client revocation option back on again. Oops In my case however, no matter how many times I tried my CMG remained well and truly broken. It’s still broken. I’ll update this post if/when I come up with a solution that works for me, but for now, this is just where I’m at with this problem and I’m blogging this as I’ve spent so many hours on it already.

if you have access to teams we can do a session to talk about this, ping me there niall AT windowsnoob DOT com, i'm based in Europe.

I replicated the same process on my test VM (decrypting with the policy and then re-encrypting using the policy), but for some reason, I’m encountering the same error message as I did on the other devices. Initially, I deployed the BitLocker policies in a smaller controller environment with VMs, and everything worked fine. I’m not sure what might be causing this issue now. The only difference I can think of is that the previous environment was running with self-signed certificates, whereas now it’s running with proper certificates. - Device status before the decryption policy is deployed. - Device status after the decryption policy was deployed and enforced. - Trying to re-encrypt after a successful decryption. - BitlockerManagemetHandler.log file after encryption policy is deployed - After rebooting the VM, the next console login via the MSTSC.exe client shows the following: It’s important to mention that I was able to successfully encrypt and decrypt this same VM while the system was running under self-signed certificates.

The endpoints are running Windows 11 24H2. The severs infrastructure for the MP and DP are running Windows server 2019 1809.

"Apologies for not seeing your reply sooner. This doesn’t apply to the current environment, as there was no previous MBAM infrastructure. However, I did decrypt the devices using the decryption policy, since the machine was imaged and BitLocker had been enabled with a weaker encryption algorithm. The decryption policy worked flawlessly, but as previously mentioned, the encryption policy is not functioning as expected. I have made sure that the targetted devices are no longer targetted by the decryption policy.

@Cerberus24 what client OS are you testing this on as a matter of interest? I'm, happy to do a remote session to compare my lab to yours but it would be good to get more info about your setup

and it's encrypting without any interaction from me

before getting bitlocker policy added the device to my bitlocker policy collection the client has determined it is 'non compliant' for Encryption

ok imaging done, device is NOT encrypted (as I wanted), next up, i'll add it to a collection targeted by BitLocker Encryption policy and see what happens

i'm imaging a VM now and will let it complete, once done i'll drop it un-encrypted into a collection targeted with BitLocker policy, i'll share my results here once done

i'll double check in my https 2409 lab this evening and report back have you verified that these devices are not targeted by any gpo from your 'old' mbam infrastructure ?

Yes, I’ve tried that as well, but I’m still getting the same error message. One thing I didn’t mention earlier is that I’m running this ENV on HTTPS, but as far as I can tell, the certificates are all working properly.

can you logon locally to a test device to verify encryption ?

Hi, there is no CD/DCD in the tray, nor is there an ISO mounted on the system. Correct, I initiated a console login through Microsoft RDP to check the encryption process, but I always receive the following error message described below.
