Hi Everyone,
I am having a problem with RDP on three Windows XP SP3 machines. they are connecting to a Windows Server 2008R2 terminal server. The odd part is there is another Windows Server 2008R2 that is used for something else and is one of the DC's. I used this server to make the RDP settings changes (to test with as not to screw up the TS) and now can't RDP into the TS.
I changed the server RDP settings to allow only connections from computers using network level authentication and I updated the XP RDP to 7.0 but now when I try to connect I get "an authentication error has occurred(code:0x80090303)
I have also turned on the CredSSP for each XP machine.
When I first made the changes, turned on CredSSP and updated to RDP on the XP machines, I then tested and it seemed to work, I was able to RDP to the Servers, I tested RDP to both. It's been about 6 hours since I made the changes.
Thanks
Danny
