>>Hi,
>>
>>I have an application that I recently installed at a client's site on their network. The PCs are part of a work group. The data is installed in one PC's Public Folder and access granted to the other PCs. Each PC has its own executable on its hard drive and I believe is running Windows Vista.
>>
>>The PC with the data on it runs fine all the time.
>>
>>The other PC runs fine if the first PC is not running the application. If the first PC is running the app and I try to start the app on the second PC, it hangs, if the app is shutdown on the first PC at this point in time, the second PC then continues to run. If the second PC runs the app first and then the first PC starts the app, the second PC will run for a little while fine, then it will "hang" until we shut down the app on the first PC then continue along fine.
>>
>>If I had to guess, this looks like some sort of SET REPROCESS thing, but nothing is opened exclusively nor locked as far as I know and the application runs fine on other networks (I think they have a third PC so I will try to get them to bring that one into the mix and see what happens).
>>
>>I tried to duplicate the problem on my hardware unsuccessfully
>>
>>Does anyone have any idea what could possibly cause this?

>Historically, one cause of this has been antivirus. You could try testing with real-time scanning disabled on both PCs, or exclude VFP data and temp file folders from scanning.

>Also, Vista talking to Vista peer-to-peer will use SMB2, which AFAIK will eventually cause data corruption problems with VFP tables. You may want to disable SMB2:
