DNS Suffix Issue

Hi

Windows 7 Pro Opsys

We have a local network with workstations and servers in a W2003 domain. The workstations are going to move to another AD domain (controlled by others) but still need access to the local servers in the original AD domain. Note that these servers may also move elsewhere soon with a consequent change of IP.
The problem I have is that PCs in the new domain have greyed out DNS Suffix Search order (with a number of domain entries) so I can't put our existing server domain in the list (at least via the GUI in the networking section as per normal). When someone tries to access a server by its hostname rather than FQDN, resolution fails as it goes through the greyed out list and fails to match the servers name with any domain.
Why/how is the DNS Suffix search list greyed out and how can I add the server domain to the DNS suffix list?

Thanks

The answer is that we amend the local hosts file of each PC with entries for key local servers. It is only a temporary measure so that will do the job.

Hi,
it may be greyed out because of a Group Policy options from the domain controller they belong. In that case you need to administer it from Active Directory

hope this helps

That's what I thought. Just wondered if there was any way I could add an entry to the list as local admin.

Yes i believe you can, but as soon as you logon to the domain it will overwrite your settings.
Chances are that the administrator might have put settings on local profile as well.
Anyway, by logging in with local profile (administrators group) you can change settings.

We opted to edit the local hosts file to get around the problem
