26.Jan.2011 | by Gusac | Filed in: Articles, Troubleshoot

Issue: While connecting a server through remote desktop, you get the login screen but after entering the login credential you get the error message: ‘RPC Server Unavailable’ and it does not let you login.

In Application logs, we get error with event id 1219, Source: Winlogon and the description of the event is: ‘Logon rejected for <user name>. Unable to obtain Terminal Server User Configuration.’

Things to check:

  • Create the Following DWORD value and set it to 1

    HKeyLocalMachine\SYSTEM\CurrentControlSet\Control\Terminal Server

      IgnoreRegUserConfigErrors =1
  • Roaming Profiles – Test with an account that has local profile. Reference: KB 821929
  • Network Binding Order
  • Disable TCP Chimney and RSS on the network adapter. Reference KB 948496
  • Incorrect DNS server configuration on the server.
