DCDIAG in SBS2003 returns no data

I have recently been experiencing some problems with a SBS 2003 DC in that it would not replicate with its partner and the ntfrs service never managed to get to log event 13516.  At the time I was using DCDIAG to help me find the problem. I decided that the issue was with the replication partner DC which, since it served little pupose in our organisation as a DC, I decided to demote.  I was then in a catch 22 becuase I could not log on to the secondary DC to demote it because it claimed it could not find a DC!  I then tried ADSiEdit to remove the secondary DC and although this seemed to get rid of it I still could get a 13516 event.

I eventually forced the replication to complete by changing the Burflags registry entry to D4 and manually restarting the ntfrs service. After that I was able to log on to the secondary DC and demote it properly.

Now I want to run DCDIAG on the main DC to confirm all is OK and this is all I get:
C:\Documents and Settings\Administrator.CTS>dcdiag /v

Domain Controller Diagnosis

Performing initial setup:
   * Verifying that the local machine Chromis, is a DC.
   * Connecting to directory service on server Chromis.
   * Collecting site info.

Nothing else at all!   I don't know where to start to rectify this. I am worried that I mat have screwed something with ADSiEdit but the DC seems to be working as expected.

It seems that within Active Directory Sites and Services, within Default-first-sitename/Servers/<server> there was no "NTDS Settings" object.  Once manually recreated dcdiag worked again.

My first suggestion is to download the SBS 2003 BPA at www.sbsbpa.com and run it and fix everything it finds...then see where you're at.

Yes we have BPA installed already. Nothing of note on there - certainly nothing that wasn't already there prior to this problem.

well if this were me...I'd make sure all DATA is backed up, export your email, and so on  all to USB drives....you could do a system state but I'm not sure how valid it would be
Then I think I'd spend the 245.00 and make the call the MS Support...and try to get this server back up on it's feet...
Or bring up a whole new domain on SBS 2008...
Somethings going to go wrong in the middle of the night or a weekend and your options will be limited at that point.
Just out of curiosity..have you run NETDIAG?
How many nics in this box?    Could you run and post the unedited IPCONFIG /ALL from the server?

Actually we are in the process of doing a Swing migration to SBS 2008 but of course we want to ensure that we are not migrating rubbish.

NETDIAG returns everything as PASSED or SKIPPED. No failures.

Two NICs - one disabled.

This certainly looks in order   and I'm guessing you have no name resolution issues?
You may also want to verify that SBS is holding all the FSMO roles http://www.petri.co.il/determining_fsmo_role_holders.htm
You may also find this link helpful in troubleshooting the event you're getting in the logs.

I am a bit puzzled by the information concerning the 13516 event.  That event is a good thing to see - when we were not seeing it we had problems because the ntfrs service was not completing its job. Event 13516 appearing in the logs (eventually) was a source of much relief since it meant a successful replication and return to a working DC.

FMSO roles seem OK:
Server "chromis" knows about 5 roles
Schema - CN=NTDS Settings,CN=CHROMIS,CN=Servers,CN=Default-First-Site-Name,CN=Si
tes,CN=Configuration,DC=CoralTree,DC=local
Domain - CN=NTDS Settings,CN=CHROMIS,CN=Servers,CN=Default-First-Site-Name,CN=Si
tes,CN=Configuration,DC=CoralTree,DC=local
PDC - CN=NTDS Settings,CN=CHROMIS,CN=Servers,CN=Default-First-Site-Name,CN=Sites
,CN=Configuration,DC=CoralTree,DC=local
RID - CN=NTDS Settings,CN=CHROMIS,CN=Servers,CN=Default-First-Site-Name,CN=Sites
,CN=Configuration,DC=CoralTree,DC=local
Infrastructure - CN=NTDS Settings,CN=CHROMIS,CN=Servers,CN=Default-First-Site-Na
me,CN=Sites,CN=Configuration,DC=CoralTree,DC=local

The puzzling this is that the server is behaving perfectly in every regard as far as I can see - except the DCDIAG tool :-(

I have never resorted to MS support before, but if we have to do you know my first port of call online?
