When I try to ping the server (192.168.1.100) from a workstation (192.168.1.200), I get "Request timed out".
Sounds like you have basic network connectivity problems.
Is this a new install or was this working and suddenly stopped.
If it was working what changes did you make (anywhere) ?
Have you checked your network cables etc ?
Also try this, at a workstation DOS prompt do
ipconfig /all
and report back the details here.
