NTVDM Causes Full CPU Utilization

    One of my clients is running Windows Server 2003. We have
    it setup as a Application type Terminal Services server.
    The main program we need to run on the Terminal Services
    clients is a DOS accounting package called Real World
    Accounting. The client was complaining of extremely slow
    performance when remote clients were connected to server.
    Upon examination, determined that the reason for such
    slowness was that NTVDM.exe was causing CPU utilization of
    about 97-99%. I read that running the app in full screen
    mode may help the issue but when trying to switch to full
    screen mode we get the following message "the video device
    failed to initialize for fullscreen mode" I specified in
    the shortcut to run in full screen mode but this made no
    difference.

    I used both the Terminal Service client connection manager
    v5.00 and the new Remote Desktop Connection client which
    comes with XP and had the same results.

    This hit in performance is making it so they cannot
    utilize
    the remote connections during business hours when it is
    most important.

    Does anyone have suggestions/solutions to this issue.

    NTVDM is related to your DOS program. I hate to say it but some DOS apps
    just don't run very well on the NT family of software and there sometimes
    isn't much that can be done about it.

    Having said all that, have you looked at tips # 1227 and 0151 at
    www.jsiinc.com? Good troubleshooting steps there for things like this which
    might help. If working through these doesn't help then I think you've just
    got one of those badly behaved apps I was talking about.
