Guys, I was running server 2003 PDC at my work place,yesterday after a unaccepted auto restart the AD wont start at all,DNS also stoped working,if i change the primary DNS IP address on server with my ADC's IP then the AD works fine,but with its own IP as the primary DNS it will not work if i restart.please give some ideas to recover from this Regards Jana Regards Jana

What do you mean "it stops working". And what is this ADC IP you talk about? You have a Windows 2003 DC? It is also running DNS for that domain. If so, it should be pointed to itself as Primary DNS server. Give a bit more detail about your set up and we might be able to help a bit more.

Glen, thanks for your reply. PDC(10.1.7.28) windows server 2003 mail server(10.1.7.24) exchange server 2003 two ADC are in remote area-don my PDC had the follwoing IP CONFIG ------ IP ADD 10.1.7.28 SUBNET 255.255.255.0 GW 10.1.7.1 PRIM DNS 10.1.7.28 SEN DNS (BLANK) ------- the above was the ip conf before the server auto restart(crash) after that the active Directory Refuse to start in the PDS with that ip config, if i change the PRI DNS ip on the PDC to 10.1.7.24(mail server) then i can open active Directory. if i change it back then the problem comes again now the PDC is running with mail servers ip as DNS. all the resolving are done by mail server not PDC. Regards Jana
