No Response VPN Client Connect Requests After RRAS Active for a Ti

    I have a Windows 2003 Server, acting as a RRAS VPN Server (with a NIC
    dedicated for this purpose), as well as a LAN Server (with a separate NIC for
    this purpose). On System Startup, VPN Clients can connect successfully, and
    remain connected for many hours, sometimes even days, without problems.

    However, at some point in time, the server will begin to not respond to any
    new VPN connection requests, even though there may be only one active VPN
    connection, that has been connected for a long time. Then, after this
    situation has developed, if the existing active VPN connection happens to
    lose connection for any reason, there will be no response to its attempt to
    re-connect, and no response to any other VPN connection requests.

    In these cases, I can see the incoming network activity on the server's VPN
    NIC monitor, but I do not see any outgoing network activity, and the VPN
    Client displays "There was no answer"

    Re-starting RRAS corrects the problem.

    Does anyone have any ideas on how I can fix this problem? Thanks.

  2. Can we presume it's W2k3 SP2 + all updates from update site?

    It is Win2k3 SP2, with one missing update.

    In verifying that all updates had been installed, I found that KB948496 had
    not been installed. Since that is the update for the SNP Pack that was
    included in SP2, it may indeed have some bearing on my issue.

    I'll install the update, and we'll see if that corrects the problem. It
    will no doubt take some time to confirm a fix / no-fix conclusion, since the
    problem had been sporadic. Hence, for the purposes of this post, I'll assume
    that the update has it fixed, and create a new post, if I find that the
    problem was not fixed.

    Thanks for your help.

  4. That SNP-related hotfix was the one that i was shooting at.

    It's highly recommended for EVERYBODY with network problems :)
