can anyone tell me the solution for my problem.

we have TWO windows 2003 enterprise servers. one named as HRDC (domain controller) with DNS server and other named HRDB as database server (oracle). every thing was working fine for around 3 weeks. now nobody can access the HRDB server with its name. but we can access it its ip address. we can ping it using name and ip.

can someone tell me how i can solve this. :blink:
