Remote Desktop: the logon attempt failed

I was unable to save my credentials just for one server. This server was NOT a domain member, domain member servers doesn’t suffer from this issue (in my case). Remote Desktop (mstsc) keeps asking for credentials all the time, with the error message:

Your credentials did not work
Your system administrator does not allow the use of saved credentials to log on to the remote computer <serverName> cause its identity is not fully verified. Please enter new credentials.

the logon attempt failed

RDP - the logon attempt failed

Had this issue a long time, but today was the day to tackle this issue. I found the solution here:

  • Open Group Policy Editor via cmd -> gpedit.msc
  • Navigate to Local Computer Policy\Computer Configuration\Administrative Templates\System\Credentials Delegation\
  • Open Setting Allow Delegating Saved Credentials with NTLM-only Server Authentication, set it to Enabled click on button Show… and in Show Contents window add Value TERMSRV/*
  • run a gpupdate on your workstation

This solution works, but I had to make a new group policy object (GPO) in my Active Directory Server because my Windows 7 is a domain member.
