AutoCAD won't get a license from network

One morning you fire up your AutoCAD and it tells you it can't obtain a license from the network. What happened?

Usually this occurs when the server machine has been restarted. Automatic updates from Windows, power outages or someone just plain turning off the machine could be the culprit.
Here's what to do:

1. On the server go to Start-All Programs-Autodesk-Network License Manager-LMTools

2. Go to the Server Status tab and press the 'Perform Status Enquiry' button. This will give you a readout telling you whether there are errors. If there are errors...

3. Go to the Start/Stop/Reread tab and press the buttons in the following order; Stop Server then Start Server.

4. Go Back to the Server status tab and press the 'Perform Status Enquiry' button. This will give you a readout telling you whether licenses are available and how many.
