can't access shares from some computers

I restarted the server (windows 2003) and now some of the workstations can't access the shares anymore. I restarted it again but still have the same issue.
the weird thing is that it will reconnect the drive randomly during the day.
Note that I can ping the server from all the workstation.
there is no firewall on the server and the turn off the AV just to see but that was working with it before
there is no error messages on the log events and here is what I did:
add the DNS to the host file.
run winsock
connect the server to a different switch.
connect it using the second network interface

please I need your help

thanks

When you say you are able to ping the server is this by name or by ip?

Are you using DHCP for assigning IP addresses or are they assigned manually?

From a command prompt can you run ipconfig /all from a workstation and from the server and post the results

can you check in the DNS console in the forward lookuo zone to see if there are any duplicate entries for your server?

I can ping both name and IP

I am using DHCP on the server and there is no duplicate in the DNS...

I will give you the ipconfig /all tomorrow morning when I get to the office

ok so I found the issue. we used to have symantec endpoint and it seems that it was not uninstalled all the way even if there were no more trace of it.
I found out when I checked the network conenction properties and found under this connection uses the following items: something called Teefer2. I googled that and found that it was related to endpoint. I then went through that process http://service1.symantec.com/support/ent-security.nsf/854fa02b4f5013678825731a007d06af/5db8e519e16d42f2882573290005aa1d?OpenDocument
and after restarting the server everything is fine again.

not sure why it started yesterday though and not a month ago

please close this threat
