Validations:

Despool.log has nothing relevant to note.

I have checked these things already and ANSWER is YES to all of these questions :

Can you ping the affected SERVERNAME if the path is a UNC path?
Does the site server computer account have permissions to access the path?
Can you access the affected path using the FQDN/NetBIOS/IP address when using the SYSTEM account from the site server?
Can you access the affected path using the FQDN/NetBIOS/IP address when using the logged in user's account from the site server?
Is there a firewall between the site server and the affected server? Are relevant ports (RPC/SMB) open?
