Are you getting the "Invalid Drive Specification"? If so, it may be that the scheduler service is running under a different user ID, and probably
doesn't have the drives mapped from the batch file. Try to use UNCs to
avoid this...

Firs off, it sounds like the batch files are getting stuck, and waiting for some user input or some sort of interaction. If you don't set the "Interactive" option, you will not be able to see what's going on. So, I would suggest that you use redirection and redirect the ouput of each command in your batch file into a logfile, so you can better see whats going on.

Remember, such things as drive mappings and user varables only exist when you are logged on, if nobody is logged drive mappings donot existnor do user variables such as %TEMP%, etc. To overcome this you would need to use UNC pathnames or map the drives as part of the batch file; and set the variables as well.

Also very important is the account that is used for the Schedule Service. If you use the "System" accnt, you will have only access to the local machine. Using a Domain Admin accnt will give you access to other machines on the network, provided those permissions are in place.

But I would definitely log the output of the commands in

This may not help you, but try using the winat utility from the resource kit. It is easier to make sure your AT jobs are set up correctly and are going to do what you want.

The schedule service is a little bit unstable. Instead of restarting the server you should try "stoping and restarting" the schedule service (it controles the AT-jobbs). We have to do this rather often on one of our NT 4.0 sp3 servers. Starting and stoping services can be done through the servermanager, so you dont have to visit the site :-)

I have found that the AT command runs best from a remote location...make sure the scudual service is started and I would also suggest the NT resource kit tool "WINAT" this will turn this proccess into a GUI and make schudualing several jobs on remote computers very easy...also it puts everything into a very managable View.
