Disconnecting network drives

Microsoft Windows
We experience exact problem with the disconnecting network drive( red X) as specified in MS article KB297684. http://support.microsoft.com/kb/297684/en-us The file server is win2k3 sp1 and the home drive is mapped by VB script. It is not a big issue when browsing or accessing the drive as it gets connected quickly. The problem is when a program tries to access the drive, it is unable. I wish to modify the registry to increase the default time-out period.Have anyone done this before?It is our major production file server and I want to make sure that this change does not impact on the server performance. I can try it on our test server, but i will not be able to test the performance, since there are no resources on it.Thanks in advance.

Thanks. We'll let you know when a new response is added.

This change should not have any negative impact on the performance of the server. In fact if you turn it off, it may actually improve it, since the Server service doesn’t have to use any (CPU or memory) resources to accomplish this.

    You have the answer- the autodisconnect or "ghosting" of the drive connections is just there to save resources on the server. MS tends to think in terms of big companies like GE or GM when they do stuff like this where server may have hundres or thousands of users connected. If you don't have a ton of users, it's probably fine to set the timeout to a higher value. Alternatively, you might just write a really simple batch program as a scheduled task that just tries a "dir" command and makes the drive reconnect on a periodic basis. There may be a more elegant way to do this programmatically in your app that doesn't like the disconnected drive to. Is it possible that your app just doesn't have a high enough timeout waiting for the drive to reconnect or is your program just querying it's state and getting pissed if it's "disconnected" before even trying to connect. Good programming always means good exception handling and logging and hopefully yours can report what the cause is so you can fix it and make the prog happy!
