Unable to view or connect to shares on Server 2008

I have a client with a Windows Server 2008, occasionally and within 3 weeks
of reboot, all clients lose connection and cannot view shares on a Windows
Server 2008 x64 Standard. Net view from the server itself displays the
shares, from other machines you get system error 64 or system error 53. The
Firewall has been disabled, and you can still ping the server and connect by
remote desktop.

NICs are Intel Pro 1000 PT Dual port with second port disabled, and the
latest drivers.

Hi Kevin,

I hope all is well!

Have you tried teaming the NIC ports?

Are there any event log errors on the server or clients?

What I'm looking for are LSA errors on the client side. If there are LSA
errors on the client, and you reboot the client, is it then able to connect
to the share? If so, that can possibly point (conjecture) to a kerb ticket
renewal issue.

I've seen other discussions on this that point to a background session
resource cleanup blocked by a device driver on the server side. But then
again, that is like finding a needle in a haystack...

Forgot to ask, any 3rd party installed on the server, such as AV and such?

Hello Kevin D. Goodknecht [MVP],

Check about TCP Chimney offload and some other new features that are enabled
by default:
http://support.microsoft.com/kb/951037

These settings can conflict some time in the network with older OS version.
