-15, 10. System Error: 10061WinSock: Connection refused
This Rational Licensing technote discusses an issue that happens when you run lmutil on Windows 2008 and Windows 7 OS. It will fail with this error message:
lmgrd is not running: Cannot connect to license server system. (-15,10:10061 "WinSock: Connection refused"
