I am having problems where all my Windows 2003 servers cannot rpc to 2 of my Windows 7 workstations, error message is "The specified server cannot perform the requested operation".
All the machines are in workgroup environment.
Windows 7 workstations: desk1, desk2, desk3, desk4, desk5, desk6
Windows 2003 servers: server1, server2, server3, server4, server5
Windows 2008 server: server6
From any Windows 7 workstation I can rpc to any other machines, \\desk1\d$, no problem
From any Windows 2003 server I can rpc to all the machines exception desk4 and desk5, they give the "The specified server cannot perform the requested operation". However, desk4 and desk5 can rpc to any other machines (including the Windows 2003 servers), no problem
From Windows 2008 rpc to desk4 and desk5 also no problem.
I also have no problem rpc between any of the Windows 2003 servers, \\server2\d$ from server3, no problem.
I turned off the firewall at desk5 and desk4, just to try, but didn't help, same problem. This show firewall is not the cause of the problem.
Desk4 and Desk5 used to run Windows 2012 for 1 year and recently I downgraded them Windows 7 Professional x64. When they were running as Windows 2012, those Windows 2003 servers have no problem rpc to desk5 and desk4.
The issue is thus lying between desk4 and desk5 with Windows 2003 only\
Any suggestions?
