This is the case: SBS 2003 Premium, SP2. Fully updated and in normal operation. A W2000 Server is the SDC.

I re-started the SBS 2003 after changes to the registry to try to solve a problem with JUNK mail ( After re-starting, I couldn't launch Active Directory Users and Computers (I do not have the complete error now).
I ran DCDIAG (results attached) and looked into logs.

Found some events: 1126 under Directory Service log (error 1.txt) and saw some 1863s from 2 months ago (error 2.txt).

Access through he DC was normal an ADUC worked with no problems from the BDC.

I re-stated the SS 2003 server and now everything seems to be OK.

Question: Should I be concerned? What kind of preventive actions should I perform?

Thanks in advanced.

First and foremost, make sure the NIC has it's own IP address or as the DNS server, there should be no other entries.

Once that's done, go in to the DNS console and rigt click on the forward lookup zone for your internal DNS, change the updates to Secure and Non-Secure.

Then in a command prompt run the following 5 commands:


Then check the DNS console, are the zones recreated?

demazter: Thanks. I will do that later today.

Allow me to ask, do any of the steps above make irreversible changes?

I am attaching a current DCDIAG results (just in case).
