Problem with preexec ?

[Andras S. Haramasz]

Hi there,

A simple perl script creates logon batch file (%m.%u.bat) based on user’s
name, client-machine and assigns shares based on user’s primary group. It is
created on the netlogon share. The file can be something like this:

net time \\linux /set /yes
net use n: \\linux\netlogon
net use h: \\linux\homes
net use p: \\linux\public
net use t: \\linux\tmp
net use w: \\linux\Work
net use n: /d /y

If the user comes from Windows NT, XP or 2K, adding driver takes for ever
(each drive a minute or so). Coming from Windows 9x just fails with:

“Error 55: The specified resource is not available. The computer that shared
the resource might have been turned off, or the permissions might have been
changed. For more information, contact your network administrator”
Setting time and adding netlogon share is without any problem.

Interestingly enough, when preexec is not used, the same batch file from
netlogon share works no problem whatsoever.  I’d like to create those batch
files based on users, machine, etc. at logon time. Any help would be
appreciated.
Thanks. Andras
