Check for firewalls and maybe run netmon or wireshark to see if there are any issues.   What he should be seeing is

Make sure the port 3268 open in windows firewall... Try to telnet the GC server from remote host and check...

Try netstat -an |find /i "3268" on the gc
If still don't find it listening that means port is not open; try opening the port using this article  
http://www.2x.com/blog/2010/04/tech/configuring-the-windows-server-2008-r2-firewall-to-open-ports-for-2x-solutions/

If its the remote connection problem you're looking at then try port forwarding at the network firewall on which ever device you've at place.

This is absolutely bizare, the firewall ports on the switches are open, its on the server that i get not listenning, I checked the windows Firewall - advanced and 3268 and 3269 is open.. Yest the Active Diretory Web services, also is complaining about the ports not open. This must be something in Windows 2008... Grrrr. I'm chasing a ghost here and unfortunately, I found the same issues on a few other 2008 machines and some 2008 machines don't have this problem.

I did netstat -ano and I did not see at all the 3268 port in use.
