Network path not find

I have a small network, running on a domain with all my computers having static IP addresses.I had a system crash on one os the workstation and I had to re-install the operating system(Win 2000 Prof.)
After the installation and trying to join the domain the system was telling me that network path not find.
Meanwhile, when I used a workgroup with the static IP address, i am able to browse the internet but can not join the domain.
What do I do, If that PC does not join the domain, then my policies for the domain will not affect that PC.
