VB SCRIPT ERRORS "Input past end of file" and "Permission Denied"

Hello all,

Im running this script to monitor logon/logoff activity in my network.
The script runs fine (it documents everything in my log file.

However, i get 2 errors on my clients.

error : Permission denied (800A0046)
line 121

and

error :Input past end of file (800a003e)
line 118

i have given full access to all clients to the log file.

Any help will be much appreciated.
Thanks.
