We have a small office with 9 XP desktops that have been accessing a workgroup share on our Dell PowerEdge sc430 running Server 2003 for at least 3 years now with no problems. The Server has a static IP - all desktops are DHCP.
Over the past few days there have been intermittent connection problems with the desktops connecting to the main share on the Server.
In the workgroup list under Network Neighborhood, the list of all machines on the network shows up just fine from the XP desktops.. But clicking on the Server share results in an hourglass and sometimes crashes Explorer, with no error message. This happens with ALL the desktops at the same time. While this connection problem to the Server is occurring, the desktops have no trouble accessing other shares on the network (other XP machines)
The Server also has no problem accessing shares on the desktop machines during this trouble. But the Server also gets an hourglass with no response in Explorer if I click on the Server share from the Server.
A reboot of the Server fixes the problem - anywhere from 2-12 hours - then the trouble connecting from the desktops starts again.
Two things I have tried (that might get reset on a reboot?): Unchecking and re-checking File and Printer sharing for the NIC on the Server; and doing a Repair from the NIC Property sheet. Neither one helped.
I have tried Mapping a drive to the Server share from the XP desktops - with \\Server\Share and \\192.168.1.10\Share - neither works.
Using Browstat, I've discovered the Master Browser is one of the XP machines that is always turned on, and the backup Browser is on the Server.
But from what I've read so far, if you're having trouble with the Master Browser, you should still be able to Map a drive - correct me if I'm wrong.
I'm not a networking expert, but I can't see any errors in the System or Application logs that might give a clue.
The only software change made recently on the Server was an upgrade 3 weeks ago to our Anti-Virus: Trend Worry-Free Security Standard - from version 5.1 to 6.0. We do not use the Trend firewall component.
Thanks for reading this far!
