    I'm quite happpy to find this discusion, seems I'm not alone in the universe
    anymore! I have been dealing with a very similar issue with my static gateway
    setting changing or getting lost for awhile now. I can't be sure since I
    just raised this server around the beginning of May but it sure seems to
    start the same time as what is mentioned here.

    I don't know if it help elimiante the possibility of this being a dual
    nic/dual gateway issue for Blake or not, but my WS2K3 sever has a single nic,
    though I'm afraid the rest of the network it's as simple. Here is my post
    from the SBS2K3 newsgroup. Normally I wouldn't cross post but this seems to
    be the same issue and everyone over there seems stumped by this.

    Here's the story:

    I have SBS2K3 STD (single nic) with about 20 users. This has been up and
    running smoothly for well over a year. Recently my domain got split into two
    sites. I have a pair of cisco pix 501's connecting them via ipsec aes-128 VPN
    (T1 lines).
    I have a couple apps that users need to reach across the vpn, both
    main-to-remote and remote-to-main. I have a Termial Server at the main site
    to allow offsite use of these apps and this had worked for some time with no
    problem. My new server at the remote site "Empire" is to be setup with File
    Server, Print Server, TS for Apps, and DHCP duties for the 192.168.17.x
    subnet. This is the WS2K3 box loosing it's gateway setting.

    At the main site (192.168.16.x) I have:
    Pix 501 (.1) VPN endpoint - gateway for 16.x subnet
    SBS2K3 DC - TS License Server 5 users (.2)
    WS2K3 STD - SQL Server (.3)
    WS2K3 STD - Terminal Server - Print Server (.4)

    At the remote site (192.168.17.x) I have:
    Pix 501 (.1) - VPN endpoint - gateway for 17.x subnet, DHCP server
    WS2K3 STD - "Empire" File Server, Print Server (.2)
    (will add TS for App, DHCP to Empire once this gateway issue is fixed)

    Server Empire is setup with static IP and DNS settings (as are all my
    servers) but every time I connect to it via RDC (mstsc.exe) the gateway
    setting changes from 192.168.17.1 to 192.168.16.1, I've even had times when
    it was just goes blank.

    I haven't set it up Empire as a TS yet, but this single connction should be
    fine in
    admin mode. I've checked for extra disconnected users etc.
    I'm using the Pix for DHCP duty only because I'm having issues with the
    server and didn't want to add any more roles, making troubleshooting harder.
    Workstations in the 17.x subnet all work fine. (All my workstations are
    XPsp2).

    I have checked and rechecked everything I can think of. If I do not remotely
    connect to the server the gateway retains it's setting. I can log in at the
    console
    (as several different users) and it doesn't change. I can connect remotely
    from Empire to other servers and workstation and it doesn't change. It
    changes whether I
    initiate the RDC from the 17.X subnet (locally) or from the 16.x subnet (on
    the other side of the vpn). I don't see anything in the DC logs.


    Here is the ipconfig /all for the server:
    (the 192.168.16.2 DNS server is my SBS2K3 DC box)
