I have two Windows 2008 R2 servers. One is in the domain and the other is not. I am able to access non-domain server from domain server through windows explorer using ip but not the other way around. I am able to ping the ip of the domain server from non-domain server with no problem but unable to get into the domain server through windows explorer from non-domain server. I am able to browse to the same domain server from anywhere inside the domain using windows explorer.

When I did diagnostics, it says: 

Issue found

Your computer appears to be correctly configured but the device or resource (x.x.x.x ip of the domain server) is not responding.

I know for sure that the file and printer service is turned on on the domain server because I am able to windows explorer into the domain server from any computers inside the domain.

Any clue or suggestion that I can look into the issue?

Thank you very much!!!

Hi,

Is there any error message in the Event Log? Please try to disable fast logon optimization in gpo.
