Check for RID Master

Try to see if you have a RID Master Role which assigns the
RID Pool. If you dont, you will have to assign that role
to one of the DCs in your domain by using the NTDSUTIL
tool. No RID Pool means no RID Master. Also if you dont
have a RID Master assigning the RID Pools then you will
not be able to create SIDs which will prevent you from
creating security-enabled objects.

If it shows up here:
netdom query fsmo

Schema owner pusd-ad.pomonausd
Domain role owner pusd-ad.pomonausd
PDC role pusd-ad.pomonausd
RID pool manager pusd-ad.pomonausd
Infrastructure owner pusd-ad.pomonausd
The command completed successfully.


Doesn't that mean the role is assigned?

Thanks,

If that machine is up and running then you have a RIDMaster. This is going
to be a DNS issue -even though you've done some thorough tests!!! DCs get
512 RIDs when they become a DC, and request another 512 when this drops
below 100. If you've run out it's probably because your DC cannot find and
therefore contact the RID master.

Check DNS again. I'm afraid I only know what BIND is and have never used
it, so my help on that front is going to be limited ;-(

Thanks. That's where I'm leaning but not familiar with the MS version of
DNS or how exactly the DCs find the RIDMaster.

All 'non-standard' lookups, i.e. any type of lookup that isn't a flat
hostname (or CNAME) to IP is done through the SRV records. DCs, GCs, etc.
are located through the _ldap, _gc, etc. SRV zones.

I've not yet read exactly how the FSMO roles are located -I assume each DC
carries an attribute with that info. on.

Are you experiencing any replication issues? Are your clients able to find
a DC (nltest /dsgetdc:yourDomain.com)? Are they able to ascertain their
correct site (nltest /dsgetsite)?

No, no replication problems. In fact, when I moved all the FSMO roles
and the GC to a different DC we were again able to create accounts.
Someone suggested corrupt metadata or an old replicating DC that was
offline. We did have a computer that used to be a BDC (under NT4) that
had died in January so I deleted that from the directory as well.

Thanks,

I notice that you're involved in a discussion with Ace re. a single-label
domain name. I guess that explains a few things. I'll leave this thread be
then. ;-)
