[novkhan]

Goodday

OS: 2000 advance server
Please Help
Active Directory not working.
Every Time i dbl click on ACtive Directory Users and Computers
It pop up this error message

" Naming Inofrmation cannot be loacted because:
The specified domain either does not exist ir could not be contacted. Contact your system administrator
to verify that your domain is properly configured and is currently online."

Please help.
AD used to be working fine.

Please explain in detail. I not so familiar with staff from adminstrative tools

I have tried to restart my window time
But it did not work.

And i also suspect it might be my dns problem.

I did a nslookup on the DNS server and it reply
"cant find server name for address 10.x.x.x : Non existent domain
Default servers are not available
Default Server : Unknown
Address : 10.0.0.2 ]

Please tell me how to slove , if it is a DNS problem.

When i did this DCpromo . It says Welcome to Active Directory Installation Services, when i click next, It states " Remove Active Directory"....? Why do i have to remove Active Driectory???

When i type Ipconfig/all, this is what i get.

Windows 2000 IP configuration
hostname: Benq
Primary DNS Suffix : ABC.com
Node type Hybrid
IP routing Enabled : Yes
Wins Proxy Enabled : No
DNS Suffix Search List : 10.0.0.12 <-----Benq IP address

Additional info:
I set TCP/IP properties to" Obtain address automatically" & "Obtain DNS server automatically".
