network issues - systems keep locking up

i have the following:

new server with windows server 2003 r2 sp2
    single 10k hard drive
3 workstations Windows XP sp3
10/100/1000 Network Switch
all NIC cards are  10/100/1000

i have never had any problems
all of a sudden, if one workstation locks up using a program on a mapped drive, they all lock up
the eventvwr does not show anything other than it took a long amount of time to transmit data.

the workstations loose their mapped drives and have to be rebooted.

could this be because of the systems are trying to access the same mapped drive?
should i use  RAID-1 mirror  to help with data transfer rates?

i can transfer 4gb of data from the server to each work station and no lockups
so i do not believe it is network related but not sure?

if one system locks up - why would they all lockup?

anyone have this problem before?

thanks

This sounds like the server is hanging on a spin lock in the kernel.  Spin locks are normally resolved very quickly.  However, if there are unexpected problems such as recoverable bad blocks on drives, the kernel may hang while the drive recovers from the problem.

Suggest you check the SMART status on the drive containing the programs/data being accessed -- Event Viewer does not show drive SMART status for recoverable errors.  On a RAID set, the RAID controller software should be able to show SMART status; on a single drive, try Passmark's Disk Checkup (freeware) to check SMART status.
