Problem browsing across subnets

    Hi all,

    We have 2 locations, connected by a dedicated T1 as follows:
    subnet A: 192.168.0.xxx (SBS server is in this subnet with XP Pro
    clients)
    subnet B: 192.168.1.xxx (no servers, only XP Pro clients)

    Users in subnet A can browse any machine in either subnet and access shares
    according to permissions set.

    Users in subnet B can see entire network but cannot browse any XP Pro
    machines in subnet A - in other words, they can see the machines listed in
    My Network Places, but they can't access at all, even to see what shares
    arre available - when doubleclicking the PC the error is "The network path
    was not found". They can browse the SBS server and a W2K server just fine.
    They can ping all machines. All computers in that subnet and all users have
    this issue, including Administrator.

    Using DHCP and WINS, all the machines are registered properly in WINS and I
    can ping no problem. I remember having a similar issue when I first set up
    the server a year ago, it was a policy on the windows firewall, but I
    checked and localhost and both subnets are still there, nothing's changed
    that I know of on the server. All clients are at same patch level via WSUS.
    All are DHCP clients.

    The only thing I can think of that HAS changed is a consultant added a video
    server in subnet B which is not a domain member, is DHCP client, and is in
    a workgroup. There are no servers on that subnet. They have no problems
    connecting to any server resources such as the internet, email, company web,
    databases or anything else - they simply can't browse workstations on the
    other subnet.

    I honestly don't know when this became a problem, it was brought to my
    attention today when a user in subnet A needed to share some files with
    someone on B and didn't want to move them to the server.

    Any ideas why this would be happening??? ipconfig info posted below.

    TIA,
    SusanV

    Resolved - re-reading my post I noticed that teh DFG on subnet A was set to
    the SBS server (WTF? Someone's been playing, time to change the admin
    password again!) Changed the scope to reflect the router for the DFG on
    subnet A and all is well.

    HAGD,
