To see who has licenses, any machine on the LAN can install the Autodesk Network License Manager. Download it from here:
They need admin privileges to install it, so you’ll probably have to log in as UserAdmin to install it for them.
Next, create a Windows Environment Variable that tells the NLM where to find the license server. Instructions for doing that are here:
For the variable value, use @vmsvr.
Once that is done, there will be an icon for LMTOOLS on the desktop.
1. Double-click it to open LMTOOLS.
2. Go to the Server Status tab and click Perform Status Enquiry.
3. It takes a little bit of practice to interpret what the Enquiry says. Basically, scroll down in the result area until you see lines that include the text “ACD_F” or “IDSP_F” or “AECCOL_F”. (I may be wrong on that last one, but it will end in _F for sure.)
ACD_F is the AutoCAD license
IDSP_F is the Infrastructure Design Suite Premium license
AECCOL_F is the AEC Collection license
On those lines, it will say something like “1 license issued. 1 license in use”. This tells you how many licenses of that type the server has in total, then how many are checked out.
If a license is in use, below that will be a line with the username of the user that has the license checked out.
