Michel,

Here's a note I sent to the ACCPAC forum, which is a Visual FoxPro forum for developers. Some of these developers have had the same XP problem we are experiencing. Keith ran into this forum and this particular problem; perhaps this will solve our problem too.

"We have also been experiencing this phenomenon, which is irritating at best. We start a process through our scheduler (TimeTarget); the processes are Visual FoxPro compiled programs (.EXE) which work with data tables. After some time, the mapped drive disconnects, interrupting the process. If the process is interrupted, as has been happening continually since we installed Service Pack 1 of Windows XP, we get a message that states, "Network path no longer available". Our connection is a mapped drive through a T-1 dedicated line from our client's site to their other site.

Even trying to copy zipped files of no more than 1 or 3 MB will fail part of the way through each time. I just went into the registry (using REGEDIT.EXE) and changed the value of the following to Hexadecimal 0:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters for AutoDisconnect

I am going to test this to see if it makes any difference at all. We connect from a Windows XP Professional Operating System on which we just reinstalled Windows XP to get rid of Service Pack 1 pollution. Typically, each copy of records from one table to another fails; this did not used to happen prior to SP1. Well, so we got rid of SP1 and also changed the AutoDisconnect to 0.

I'll come back here and let y'all know what happened.

I'll tell you this, all of this XP trouble makes me wish we had used Windows 2000 Professional instead.
