Prevent NTVDM to load network driver RRS feed

  • Question

  • Hi all,

    We have some 16-bit app that used a key-file to run (should be in the app directory or search for it around). For the moment it works without a key, but it is hard-coded to look for it. And when no key is found in app directory it starts to broadcast through all the network searching for the key; 3 hours later with no success finding the key it starts. If I disable network adapter - it starts immediately.

    So is there any way to "hide" network adapter from NTVDM? Maybe the way is to prevent it to load network.drv, but how can I do that?

    Windows 7 x86 Pro environment.

    Any help would be appreciated.

  • Hi,

    In my opinion, there is no way to prevent a process load its resources. Such as NTVDM load network driver.

    It would be better to realize this feature at APP level. Maybe you could find some method to let the 16-bit app ignore network device.
