Opening documents or photos located on our file server when using hoste name (\\host_name\share_name) takes a considerable amount of time. When I do the same using IP address of the host (\\xxx.xxx.xxx.xxx\share_name) it's instantaneous.
The issue started occurring few weeks ago. Nothing has been modified on the server as far as I know that could cause the issue.
The server is Windows Server 2008 Standard 32bit, a guest machine on an EXS server. It's beeing accessed by Windows 7 clients.
The DNS information for the server seems to be correct.
I would be very grateful for some hints on how to resolve the problem.
