Global Catalog Server could not be contacted - AllGc's are down

Help!
I had an old server that ran active director and was my global catalog server.  This server was my only DC.  I put in a new server and made it an additional DC.  I then made the new server the Global Catolog server.  It has control of all 5 masters, and I have corrected DNS.  I then demoted the old server.  The server now takes two hours to boot and after running dcdiag /v I am told that the Global catalog server could not be located - all GC's are down.  I also see in event viewer/Directory services that the Global catalog server could not be found.  Please help

Was the old server Win2k and this one is Win2k3?  Also, how did you make it the global catalog server?

The old server was Win2k3 as well as the new one.  I tried to do it with operations master, but could not.  I then ran the force and when it attempted to do it befor forcing it, it came back successfull.  I then checked and my server had all 5 roles.  Then I demoted the old one.

To make it a global catalog server, did you go into Active Directory Sites and Services, and to the NTDS settings and set it as a global catalog server?

After that, you will need to force a replication between the old server and new server in order for the Global Catalog to transfer.

Additionally, take a look at the event logs on both servers to determine what may have gone wrong.

I think I just screwed up.  I went into Directory Sites and Services and no global catalog was selected. I have selected my new server as the GCS, created another DC and they have replicated. Ran dcdiag again and everything passes.  Going to reboot tonight and see what happens.  Let you know tomorrow.  Thanks

adamdrayer,

Thank you for your help.  Everything is working correctly.  I have to note that the reason the server was taking so long to reboot was due to Lotus Notes.  I did not mention that Notes server was on this server as no error was ever reported.  For some reason, notes server would be running in the back ground wating for a password.  Once the server was up, I removed the password requirement and the server now boots in less than 10 min.  Again, I want to thank you.
