Try to schedule AT across different workgroups and domains, using
AT \\servername 19:20 \\fileservername\share\aprogram.exe
And just can't get it working. AT on the same machine works fine, but as soon as \\servername is used, it fails each time. In the event log it says
"The At3.job command failed to start due to the following error:
General access denied error " - Event ID 7901. All the boxes I'm trying are 2000 and XP.
