network freezes with windows server standard 2008
Posted on 2009-04-06
We have Windows 2008 standard installed last July(2008). Even since it was set up, the network would freeze intermittently. The symptoms are: one pc uses one file on the shared network, then the PC would stop working ( in the way, task manager, mouse, keyboard, all stopped working. PC screen freezes). at the same time, other pcs, if they do not touch any of the shared information (which reside on Windows 2008 server), they are fine. but as soon as they touch the shared network, they freeze too. I tried everything. We hired consultants and they tried everything. The only solution is: if we restart the server, it would come back fine.
We tried Wireshark, changed cables, did all sorts of tests that people on related subject suggested, upgraded Symantec from Antivirus to Endpoint 11, and then upgraded with every version they released. Now we are running Endpoint 11, MR4, MP1. The newest. Still the same problem happens.
Any insight would be highly appreciated.
