Usually it is one of these: The only GCC is going down in Native Mode OR
you have DNS issues.

With a single domain forest you should make all DCs into GCs.

Then double (triple) check your DNS. The vast majority of such problems
are really DNS issues.

DNS for AD
1) Dynamic for the zone supporting AD
2) All internal DNS clients NIC\IP properties must specify SOLELY
that internal, dynamic DNS server (set.)
3) DCs and even DNS servers are DNS clients too -- see #2
4) If you have more than one Domain, every DNS server must
be able to resolve ALL domains (either directly or indirectly)

netdiag /fix

....or maybe:

dcdiag /fix

(Win2003 can do this from Support tools):
nltest /dsregdns /server:DC-ServerNameGoesHere
http://support.microsoft.com/kb/q260371/

Ensure that DNS zones/domains are fully replicated to all DNS
servers for that (internal) zone/domain.

Also useful may be running DCDiag on each DC, sending the
output to a text file, and searching for FAIL, ERROR, WARN.

Single Label domain zone names are a problem Google:
[ "SINGLE LABEL" domain names DNS 2000 | 2003 microsoft: ]
