Each student signs in with their own network username/password. That's generally a quick process though. It's launching Mastercam simultaneously that causes the problems for us. Thanks for checking Leon82. 5 should be a good number, in our testing it happens anytime we launch 3 or more at the same time. If we launch 2 at once, it's hit or miss.

Hello all, I work in IT at a college and we have an odd problem in our CAD computer lab. We currently have Mastercam 2017 installed on 25 machines and they are communicating with our license server via Nethasp (25 seat license file on the server). We can launch Mastercam, it finds the license server and loads up fine. Problem is that we can only launch the program on 1 computer at a time. Not to say that we are unable to use all 25 seats…we can. We need to physically click the desktop shortcut on each client computer about 20 seconds apart in order to have Mastercam launch on all 25 computers. 1 client needs to launch Mastercam fully before we can launch another client. If we try to launch multiple clients at the same time we get one of these errors. It’s almost like if the server is talking to 1 client (verifying the license via Nethasp), it cannot speak to any other clients until it is done with the current client. The error occurs on the splash screen after about 20 seconds of "Checking Hasp..." “Exiting…No Mastercam license found. Do you have an activation code?” “Exiting…No Mastercam products enabled on this license” This becomes a problem in a classroom environment for us since all the students log in at the same time at the beginning of class and try to launch Mastercam. The only way to get things working is to have Computer #01 launch Mastercam fully, followed by Computer #02, and so on for the next 10 minutes. This wastes a lot of time. Just wondering if anyone else out there is running a nethasp setup with multiple machines...and if so, would you mind testing this out for me in your environment? Login to a handful of machines and simultaneously launch Mastercam on them all. I'm trying to determine if it's worth it to rebuild a fresh server, or if I can fix the problem on the current server...or if this is something that happens to everyone and there is not a fix. I've contacted Mastercam support and they had me verify the nethasp.ini and nhsvr.ini settings. Also reinstalled a clean copy of the License Manager to no avail. Thanks for any help with this!
