PCs on IP range very slow login

If i right click the the server name in DNS and go to interfaces I have 2 IP addresses selected the x.x.44.1 and 192.x.x.x. I have deselected the 192.x interface and I am going to try a machine. I will let you know how i get on.
Thanks again for everybodies help.
Cheers

Cool.

You might find you get quicker results by looking at the DNS records and deleting any records pointing to the 192.x.x.x address...

Thats worked, I really appreciate your help. Thanks alot.

No worries!
