nt4 pdc drives drop off network

By dboytim ·
I have an NT4 server (pdc) every week or so all of a sudden users cannot see the network drives on the server. I have to reboot the server. There are no event log messages and the server seems to be running fine. We just moves to a new building withall new hubs and routers, however this also occured at the old building with the old swithces and routers. Any ideas?

Ive seen this happen when a switch or hub gets damaged in moving. Its also happened due to a faulty cable plant. In once instance, every couple of hours, the switch they were using as the server backbone would turn all lights orange, recycle and thus recycle the gigabyte backplane. After closer examination, the switch was actulay bent in the middle. We moved the router and servers off the switch and had it switched out from Cisco. You may have to put a sniffer on the wire to determine whats going on. Im thinking physical wire or switches as you made the point you just moved.

The need to recycle the NT box would also make sense because it re-opens any physical or logical connections that might have been closed due to errors. A sniffer on the network is in short order.

I have also seen this problem and tracked it down to inappropriate wiring. There was a lot of cable branded "LVL-4" in an area which was serviced by a 10MB hub. A 100MB hub was added and machines were slowly migrated from the old to the new hub. At first everything seemed fine. The network started to have a lot of problems as more nodes were switched. There were a lot of unreachable mapped drives, browser elections and such. Remember, within a segment, all the cable is connected to the rest of the cable and signal errors are cumulative.

This was a lesson in "Don't ignore the standards even if it seems to work."

Unfortunately, much of your wiring is hidden from view or hard to reach. I would try to check it anyway. The problemcould be the cable, termination technique, patch panels or anything else in the cable path.

Also....
Check how drives are shared....
Don't share at root($) level, create root level folders for sharing,
