SERVER CONNECTIVITY

Hi all,

I have a newly installed PC in my office.
We r having a DHCP server(win2k3)win in our network,but the thing is the pc loses connectivity with server when it is having a DYNAMIC IP & its showing a ip conflict .But i verofied no other pc or device is having the same address.
The PC works perfectly well when it have a STATIC IP.So i am looking for a solution to solve this problem.

Tanks in advance,
