FQDN leads to timeout

Hi guys

i'm stumped with this one...

I have a server that i've moved from our LAN to the DMZ. This has IIS running on it.
Everything was working fine up to today, when suddenly the FQDN leads to a timeout, though when i browse to just the host name, it works fine.

Would it have anything to do with DNS refreshing, or something like that?

Check DNS entries in advanced TCP/IP settings. Make sure you have appropriate DNS suffix entries. If not a member of the domain you need to have DNS suffix for this computer setting as well.

Another thing often missed is the System settings in the control panel. On the Computer Name tab select change and then more. Ensure your primary DNS suffix is entered here.

The server has the DNS suffix under the Computer Name in CP.

when i ping the box, i get the following:

c:\ping servername
pinging servername.domainname

so it looks as though DNS is ok. Would it be something in IIS?

IT turns out that the firewall was blocking some LDAP etc ports that were preventing the server from registering correctly.
It now is reachable with the FQDN.
