You seem to be connecting through a router with DHCP and DNS forwarding at
address 192.168.1.2 so I'm wondering why the gateway address is set to
something different (192.168.1.10)?

Our vista business laptops are loosing connection as and when , after
joining the domain. It was working fine earlier when part of a work
group.

I don't want to venture in too deep over my head in this but I'm thinking
that the router configuration might be one place to look for problems. The
router doesn't require its DHCP server to be enabled and DNS should be set
to pass through rather than relay. There's a network configuration guide at
the link below for what looks like the same as you are trying to do. I
didn't notice anything obviously wrong but a step by step through the
configurations might turn up something.

My DHCP/primary DNS server is my Domain Server and Gateway address is my

You seem to be connecting through a router with DHCP and DNS forwarding

something different (192.168.1.10)?
