When I logon as Administrator after 30sec or less I get the dialog box "Expired Credentials. Windows needs your current credentials to ensure network connectivity. Please lock this computer then unlock it using your most recent password or smart card."
Once I do this, after working for about another minute or so the error message returns. In this particular case I had logged in as Administrator to update a workstation - once the error message came up, I followed the instructions then restarted the machine as the updates were complete. After restarting the system did recognize my Administrator credentials. I had to log in via remote desktop to the server with another username that had elevated privilages, and change the Administrator password. This has only happened on two machines in the Domain. It seems it may have something to do with cached credentials but how do you go about resolving the solution? Any help is greatly appreciated. The systems that are affected are both Windows XP Pro machines connected to a domain with 10 other systems. If I login DIRECTLY to the server (not through Remote Desktop) and change the Administrator password from there will that make any difference? Thanking you in advance.
