>Sometimes I have a situation, when the file is locked, but nobody uses it in the moment. So, my questions are:
>1) Do you know, what may cause it?

Besides the network problems, if any, there is only one reason I know about - people turning off there computers w/o properly logging off.

>2) Is there a way to find out, who locked the file?

There're a few programms you can use to check it. The two I used called whohas and fileuse. You can find them on the internet. I like whohas better but for some reason it doesn't work on the fast computers. Unfortunatelly both those programms requred at least operators right to the drive maybe even Admin.

>3) Is it possible to release lock programmatically from workstation? We have Novell server and Windows 95 as workstations.

To do that you have to kill connection that has this file open and I think only Admin can do it.
