XP Client Machines Not Resolving DNS addresses

We are running Windows 2000 DNS servers with Windows XP Client machines. The clients are not resolving IP Addresses via DNS and are having to fall back on  to legacy WINS resolution which is still in place for our small Windows NT 4.0 population. The correct DNS Suffix is being applied to the clients via Group Policies but when using nslookup with just the host name we achieve the following results: -

can't find xxxxxxxxxxxxxx: Non-existent Domain

If we provide nslookup with the hostname and the domain suffix however, the address is resolved.

Our Mac OS X clients resolve the address using just the hostname when using nslookup or host.

On your XP client, open a command prompt and type an

ipconfig /all

check if the correct DNS servers and DNS suffix is displayed here.

If you have DHCP check if you set the option "Node Type" and if its set whether its set to 0x8 (Hybrid Node) or not (should be 0x8!).

Check your servers eventlog for errors regarding DNS. Post them here if you suspect a problem.

try to clear the client resolver cache by running ipconfig /flushdns before doing the nslookup duch-2508 or display the cache by ipconfig /displaydns and look for a

duch-2508

This could be your problem:

        DNS Suffix Search List. . . . . . : durham.gov.uk;dcc.durham.gov.uk;npp.
durham.gov.uk;aypc.durham.gov.uk


if I check my Xp machine (SP1), it lists the Search list entries like this:
       DNS Suffix Search List. . . . . . : durham.gov.uk
                                                     dcc.durham.gov.uk
                                                     npp.durham.gov.uk
                                                     aypc.durham.gov.uk

So check the policy setting the DNS search list or however you set it.

Michael PfisterCommented:
If you look at the help page of the DNS Client policy it states:

The values of the DNS suffixes in this setting may be set using comma-separated strings, such as "microsoft.com,serverua.microsoft.com,office.microsoft.com".

So use a comma instead of a semicolon.

Hope it helps,

Michael
