Microsoft 365 learnings

I am working on couple of exciting SCCM Projects and still learning something new every day. I have been figuring out why SCCM task sequences are not deploying to workstations. Client was showing following error prior to showing option to select task sequence. Usually, you receive error 80004005 if time is not set correctly on computer or there is mismatch between SCCM DP/Primary site time and client time. In may case issue caused due to SHA1 Certificate chain. Somehow client have not upgraded their certificate authority to Sha2 due to some limitation with one of the applications. SCCM has been configured with SHA1 Certificates.  However, i forgot to untick the box 'Require SHA-256'.As a result , Boot image was failing to communicate with SCCM Management. To fix the issue untick 'Require SHA-256 from \Administration\Overview\Site Configuration\Sites. As shown below. Happy SCCM....

SCCM site backup was failing with following error,  smsbkup.log showing following error. Cannot find the dependent writer. The dependant component cannot be backed up. AddDependentComponent(pDependency) failed. Error code = 0x80,004,005.Error description = . Error: GatherWriterMetadata failed. 1. To fix this issue  Run 'VSSAdmin list writers' command. 2. Ensure following writers listed. 3. If you identify these two writers are not listed, restart 'SQL Server VSS Writer' if SQLServierWriter' is missing or 'SMS_Site_VSS_Writer' if SMS writer is missing. 4. 'VSSAdmin list writers', ensure both services are listed. 5. start sms_site_backup service to start backup, monitor smsbkup.log, ensure backup completed successfully.

ConfigMgr 1610 Windows Store for Business Integration Failed to encrypt client secret key. Windows Store for Business Integration is failing when I attempted to integrate Windows Store for business from ConfigMgt1610 Primary Site. In my scenario SCCM MP is hosted on remote server configured with SQL replica databases. Remote MP Servers do not have ConfigMgr Console Installed. It seems installing Configmgr console might fix the issue but not sure ! I am currently seeking solution for this. I have tried Configuring WSFB integration from SCCM Primary Site without MP Role but integration failed. Also, tried from remote console on server but not site server, Integration failed. I will try to install console on DP, will inform outcome. Issue explained in  TechNet . System.Security.Cryptography.CryptographicException Failed to encrypt client secret key.
