Could it be access rights issue?

>For the first time in 20 years I am having a problem, on One PC Only, with the Pack command.
>
>The problem PC is a 3 month old Dell.
>
>The EXE crashes during a pack. Different table some times, same table other times.
>The DBF is gone but a temp file named something like: 0000345R53B1.TMP is left in the folder that turns out to be the final DBF after the Pack.
>I can rename the TMP file to DBF and it works just fine.
>
>I am assuming that the rename is causing the problem. The TMP file has no deleted recs. One of the times is where we are emptying a DBF work table with delete and then pack. The TMP is empty which the DBF should be after the Pack.
>
>The problem PC is also the server in a 2 station peer to peer network.
>
>I can do all kinds of operations that run a Pack in our EXE on the 2nd PC and it has no problems.
>
>Any guesses what could be the problem on the 1st PC?
