RDP from W11 to W11 computer fails with invalid credentials error. But credentials are correct.
Hello,
I'm unable to RDP from one W11 computer to another in a Active Directory domain environment.
The error reported in the RDP app is: The login attempt failed. Your credentials did not work.
I'm able to use the same credentials on a W10 computer and successfully RDP to the W11 'server' computer.
There are no Event 4625 errors on the W11 'client' computer.
There are no cached credentials on the client computer.
I used Test-NetConnection -ComputerName $target -Port 3389 -InformationLevel Detailed
RemoteAddress : 192.168.0.33
RemotePort : 3389
NameResolutionResults : 192.168.0.33
MatchingIPsecRules :
NetworkIsolationContext : Private Network
InterfaceAlias : Ethernet
SourceAddress : 192.168.0.10
NetRoute (NextHop) : 0.0.0.0
TcpTestSucceeded : True
I would appreciate suggestions on how to troubleshoot the authentication issue.
Thank you

Hello,
Thanks for the responses.
I eventually worked out what the issue was.
Both of the computers have been imaged (but not using sysprep).
Apparently with W11 RDP uses the computer SID, this is a change from W10.
So the resolution in my case was to use SIDCHG to change the SID.Thanks again.

Hi,
You might need to consider checking the following:
1- You may need to explicitly allow credential delegation via Group Policy as might be a missing delegation or missconfigured :
- Navigate to:
Computer Configuration > Administrative Templates > System > Credentials Delegation - Enable:
- Allow delegating saved credentials with NTLM-only server authentication
- Add TERMSRV/* to the list of allowed serve
2- Ensure using the the correct format that include the correct domain example: Domain\username or mailto:username@domain.local.
3-Check the local security Policy permissions and confirm that the user is allowed to logon via RDP:
- Run secpol.msc as admin
- Go to : Local policies > user rights assignement > Check allow log on through remote desktop services then add the user.
4-Might be a DNS resolution issue, try via the IP Address or via the hostname.
5-Try adding manually the credentials into the credential manager : Control Panel > Crendentials Manager > Windows Credentials > Add: TERMSRV/Hostname or TERMSRV/IP with correct domain credentials.
cmdkey /generic:TERMSRV/192.168.0.33 /user:DOMAIN\username /pass:yourpassword
Hopefully my troubleshooting steps helps you resolved the issue.
Good luck.

Hello,
I subsequently realised that I needed to check the destination Security Event Log, rather than the client.
There are 4625 events in the Security Log. They're unusual.
- Status/Sub Status: 0xC000006D (Generic Failure)
- Account Name / Account Domain: Blank/Empty/NULL
That is, the username and password are not being transmitted.
I've tested from a 2nd computer and the behaviour is the same.
May be obvious, but worth checking that your W11 'client' has all the relevant services running (should be three of them listed in Services manager - ensure all are running.) Also check the Firewall is allowing it through.
