Windows Server 2008 DC Not a DC?

Also, in NTDS Settings I don't have a tab to make it a Global Catalog although I did that fromt he Win2k3 server prior to demoting it.

Is the 2008 DC the only DC?
Do you have the firewall enabled on the 2008 server?
Did you transfer all the FSMO roles?
Are the clinets pointing to the 2008 for DNS?
Is the 2008 DC a Global Catalog server?

Can you run DCDiag and post the results?

Thanks for you message KenMcF,

Yes, the 2008 "now" the only DC

Firewall is "off" and all inbound/outbound rules enabled

Yes FSMO was transferred prior to removal of win2k3 dc

2008 is a GC, that tab wouldn't display until a few minutes ago

Yes, all pointing to it for DNS

Can you post DCDiag from that servr?

Can you post the output of
ipconfig /all

Also, just noticed on a desktop that that when browsing the domain it shows at SDC and in active directory it's seadwelling.com...

Just to cleanup I would remove 192.168.1.7 and 192.168.1.14
 from your DNS settings.

Can you open DNS manager and verify you have the seadwelling.com
 forward lookup zone.

Run DCDiag /fix

Look throught the event logs and you should see something like this in the directory services log.

http://www.windowsitpro.com/content/content/39959/event1119.gif

192.168.1.6 win2k8 DC
192.168.1.7 former win2k3 DC
192.168.1.14 Router

Just checked, although I'm hesitant to restart the win2k8 DC I logged out to check and the log in prompt is SDC\username not seadwelling as Active Directory is.

SDC is the netbios name of the domain. The FQDN is seadwelling.com
To verify you can go into system properties and look at the full computername.

Checked directory services event log and no trace of the 1119 entry

Removed .7 and .14 from dns as suggested

Yes, there is a seadwelling.com forward lookup zone and it contains very recent changes

Ran dcdiag /fix

i don't see a reference to SDC on the win2k8 Domain Controller, just seadwelling.com

was able to create a new user in AD, but can't use it with a computer that has logged onto domain before, says domain is unavailable.

I noticed that it was not present after the dc upgrade so i copied it over manually, will look at the msdn instructions though.

net share displays sysvol and netlong shares

loads of 1054 and 8003 in the event log
