DNS Issue?

Just noticed this over our WAN/VPN.
Windows 7 clients getting IP from DHCP are not remotely accessible using the hostname.  I can remote into them using the fully qualified domain name or ip address but never happened like this before.
Clients locally to me are fine.  I can tracert them and nslookup fine.

Ideas?

Thanks

When you type the hostname, Windows will automatically append the primary DNS suffix of your client. You can add additional DNS suffixes to the search list either through group policy or the NIC properties.

Try IPCONFIG /ALL to see a list of all suffixes on your client. If the suffix of the target clients is not in the list, then you always have to type the FQDN to connect.

Also to ensure that this is actually a DNS Suffix appending issue is trying pinging the hostname using the FQDN computer.domain.com. If you get a reply back, and you do not get a reply back when pinging the flat namespace of "computer" then DNS suffix is not appending using the FQDN.
