REMOTE DESKTOP will not save credentials on domain
I tried all GP stuff which is the most common answer to this issue, but this actually worked.
Instead, in win 7, go to Control Panel -> Credential Manager, you will see three sections:- (i) Windows Credentials; (ii) Certificate-Based Credentials and (iii) Generic Credentials.
Where is your credential for RDP is listed?
If it is listed under Windows Credentials:
Click Edit under the Windows Creditials
Either write down or take a screen shot of the creditials
delete the Windows Creditials
Manually create a new credential under Generic Credentials using the information from the Windows Creditial
