PTC Creo licensing issues
One of our clients has recently moved to Creo 3.0 after we migrated their servers to 2012r2 and 2016 boxes. We installed PTC LMAdmin on their new licensing server and added the needed licenses. When we go to the needed machines and install Creo 3.0 it discovers the license server and adds the licence however when we open any of the creo products it prompts us with the following error:
License request failed for feature
Requesting PROE_EssentialsM...
7788@LicensingServer: (-96) License server machine is down or not responding..
We have made sure PTC LMAdmin is running and that the needed machine is able to ping the server, and see its network shares. we also decied to run the reconfigure setup and entered the licensing server again, it once agian saw there was an available license on the server and added it. When opening Creo simulate it once again displays the same error as ab above. Is there something else that we are missing here?
