I wrote a program and installed it xcopy logged onto User A.
Everything works OK. When User B logs on and attempts to run a part of
the program which writes to a log file, the following error comes up.
I don't know where to begin.

The program runs on XP in a peer-to-peer network.

TIA Lars

A couple of questions:

1.  Can user B edit the file manually (e.g.: open it in Notepad, make a
change, then save the change)?
2.  Is E: a local hard drive or a mapped drive or ???

I'm not on site, but I'll get an answer to the first question by

If you want user B to be able to add to the log file via your application,
he'll  need write permissions to the file.  You should be able to grant the
user permissions to the file via Windows Explorer (right-click on file, show
properties, edit access control list on the security tab) while logged in as
a user with sufficient permissions (e.g.: an administrator).  Given that
this is happening at a client site, you may require assistance from the
client's IT staff to change the permissions on the file.
