So, a customer called to report another no interactive network license available problem. We quickly narrowed it down to a problem with the license server: it wouldn’t start. Start Server said “Server started successfully”, but Perform Status Enquiry said FLEXnet Licensing error:-15,570. Everything about the license file checked out ok: it had the right MAC address, it had the right computer name, it had the right license features. But still the server wouldn’t start.
When you click Start Server, lmtools.exe starts the service lmgrd.exe, so I filtered for all Processes that started with “lm”.
Scrolling down through the log, I soon saw a possible problem: repeated NAME NOT FOUND entries for the same file:
To check whether LMTOOLS eventually did find the protocol file, I right-clicked “C:\windows\system32\drivers\etc\protocol” and clicked Include, to include only the log entries for the protocol file.
And sure enough, the protocol file was never found. So I copied over the protocol file from my system, and then I was able to start the license server.
Without Process Monitor, the only clue I had was this one line in the LMTOOLS debug log file:
(lmgrd) Failed to open any default TCP port.
