Based on: https://learn.microsoft.com/en-us/azure/active-directory/fundamentals/service-accounts-group-managed I'm trying to implement the gMSA for the following scenario: Task Scheduler account Service account (Failover Cluster, SQL Server, ADFS, Azure AD Connect, DHCP) Would that be working for the above scenario or will cause some issues? I would appreciate any assistance you can provide.

Hi @EnterpriseArchitect , Task Scheduler account => GMSA is supported Failover Cluster => is not supported : Group Managed Service Accounts Overview SQL Server => GMSA is supported ADFS => GMSA is supported : Creating an AD FS Farm without domain admin privileges Azure AD Connect => you can use GMSA , I alreday use it in my infra DHCP => GMSA is not supported Please don't forget to mark helpful answer as accepted

Hi. Thank you for your question and reaching out. I’d be more than happy to help you with your query This should work. But what I can suggest is try to adjust your permission or the permission for the gMSA to make sure that the service account required access has it. In addition, it depends on your service accounts. You maybe need configuring Kerberos delegation so that the required authentication for the services will be provided for the gMSA. If the reply was helpful, please don’t forget to upvote or accept as answer, thank you.

Hi, while running service with GMSA, you need to keep the password blank. However, for task scheduler blank password does not work. You need to create, configure task using PowerShell if you want to run it using GMSA. Also, you can create a task with normal account and define parameters. Later, you can run the command below to replace the normal user account with GMSA schtasks /change /TN \test_gmsa_task /RU contoso\testgmsa$ /RP Note: The command is not documented in any Microsoft documents but it does it's work. However, if it does not work for some reason, you may not get support from Microsoft to troubleshoot why it does not work.

Hi @limitless technology & @thameur, How do you type in the password for gMSA when it is used as a Service account and Task Scheduler?

@Mukesh Agarwal , following your suggestion I'm getting this error:
PS C:\WINDOWS\system32> schtasks /change /TN \"Test InQuote - Stage distances CSVs" /RU domain\it015-p-dbaa00$ /RP

WARNING: When the run-as password is empty, the scheduled task may not run because of the security policy.

ERROR: The user name or password is incorrect.
I've also tried to set the principal this way:
PS C:\WINDOWS\system32> $principal = New-ScheduledTaskPrincipal -UserId 'EMEA\IT015-P-DBAA00$' -LogonType Password -RunLevel Highest

PS C:\WINDOWS\system32> Register-ScheduledTask -Action $action -Trigger $trigger -Principal $principal -TaskName "Test InQuote - Stage distances CSVs"

Register-ScheduledTask : The user name or password is incorrect.

At line:1 char:1

+ Register-ScheduledTask -Action $action -Trigger $trigger -Principal $ ...

+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

+ CategoryInfo : AuthenticationError: (PS_ScheduledTask:Root/Microsoft/...S_ScheduledTask) [Register-Sche

duledTask], CimException

+ FullyQualifiedErrorId : HRESULT 0x8007052e,Register-ScheduledTask

Any clue?
Thanks
