    OK,

    EDITED to provide more detail!

    So I have a home network … in essence a server (2003) and some clients (XP Pro) which are configured as an AD domain. On that network I also have several devices specifically an HP Jet Direct print server with a Laser Printer on it and a broadband router.

    IP’s are as follows:

    The Server:
    The server (2003) handles DNS and DHCP, DNS was installed when I created the domain controller (DCPROMO) and configured afterwards to forward to the OpenDNS servers on the internet (it's a small network so I haven't configured any reverse lookups), the server's own DNS is configured to point to itself. DHCP supplies IP, gateway & DNS settings to all clients and the server acts as file and print as well as the one and only DC. To my knowledge the server cannot resolve or ping any client on the network

    The Clients:
    Mostly XP Pro (some Linux) get DHCP supplied IP addresses (client IP's range from xxx.254) as well as gateway (router, xxx.01) & DNS (server, xxx.02). All clients have home folder connected automatically but I manually configure other shares and printers (I'm sure it could be done via domain policy). All clients can resolve and ping the server, access shares and printers, they can ping the router and have full access to the internet (browse, MSN, mail etc.). I haven't tested them all but to my knowledge no client can resolve or ping any other client on the network

    It came to a head today when I put a new 2008 core server with a static IP (xxx.03) on the network ... it is not part of the domain at present. This server can ping the domain server and the router but it cannot resolve or ping to any other device (it's 2008 core so I haven't tested printing or internet access).

    Does anyone have any idea why clients cannot see each other and the server cannot see it's clients? My suspicion is that hardware-wise my configuration is fine but that in some fashion I have not configured my DNS (possibly DHCP) properly.

    Some suggestions from colleagues so far:
    * Check DNS to see if it is registering the various clients
    * Delete DOT root (not sure how or what that does).
