Running a Windows NT Task that Requires an Active Connection to NDS
Articles and Tips: tip
01 Feb 2002
I've recently had to run a vbs script on one of my servers nightly. This normally wouldn't be a problem, but since I don't like to leave myself logged in to the console on a Windows 2000 workstation when I'm not in front of it, I found that any time the script wanted to touch data on a Novell volume, it wouldn't be connected to the tree and it would then "bomb out."
So I wrote a little utility that would check to see if there was a valid connection to the tree. If there was not, the utility would make a connection, then it would run a task that you specify in a "todo.cmd" file. Once that was completed, the utility would clear the connection and exit.
I could then have the task scheduler run this application and have it access the NetWare volumes without being logged in. I found this to be kind of nice, so I thought I would share the code for anyone in a similar tight spot. (If you use or borrow any piece of the code though, I wouldn't mind hearing from you--use the e-mail address above.)
