RDP connection gives nca_s_fault_access_denied

Question

I have 2 PCs on the same network with fixed IP addresses and firewalls turned off. Windows 7 Professional and the service running on a Windows 7 Enterprise editon. System running with DCOM service.

The problem is with the RDP server connection. I have checked the packets with Wireshark and get an error:

nca_s_fault_access_denied

I got the user privileges modified to administration rights. I can ping the 2 PCs over LAN connection.

The question is, how to fix this problem? Has anybody the same error?

Answer 1

Apparently in Vista, this had something to do with Remote RPC permissions. This may still continue with 7.

In the registry key HKLM\SYSTEM\CurrentControlSet\Control\Terminal Server add a DWORD named AllowRemoteRPC with a value of 1.

Edit: I realize that "Remote RPC" makes no sense. Don't blame me for how they word it.
