Server Slow down

Our customer is complaining of a "server slow down." It was determined that
he has two servers (Windows 2000), MAIN1 & MAIN2.

MAIN1 is functioning as a Domain Controller.

MAIN2 is functioning as a Domain Controller, DNS server (their ONLY DNS
server) and SQL Server for 250+ employees.

He states that DC changes do not sync.

MAIN2 has 2GB of RAM and that SQL Server is using aprox. 600MB of that.

The Event Log on MAIN2 shows only Event ID:12292 - SAM errors regarding
Duplicate ID's for users logging in.

If he brings MAIN1 down, it takes an unusually long amount of time to log
into the Domain.

When I last spoke with the customer, I told him to install the Support Tools
from the OS cd and run DCDIAG and let me know the results.

I'm searching for any advice on where else to look for problems that could
cause his MAIN2 server to appear to slow down when running our application
that uses SQL 2000 that's running on MAIN2.



Thanks,

James
 
ipconfig /all from both main1 and main2 would be helpful in recommending
possible solutions.

I'd put DNS on main1 too and make both DCs GC.

Click to expand...

Two DCs should replicate if both are using only the internal DNS server, no
ISP's DNS allowed in any position on any member or DC of an AD domain.
That said it would be highly recommended that both DCs have DNS installed so
that there is at least one DNS server available at all times, as long as
both DCs are not restarted simultaneously.
If you install DNS on the second DC use it for the alternate DNS on both and
leave the first DC as the preferred on both.
