I am having ArcGIS desktop 9.3 version in windows XP operating system. The license was working fine without any issues. But recently I am getting an error message "FLEXnet Licensing error:-15,10. System Error: 10049 "WinSock: Invalid address", and having problem opening ArcGIS. I tried everything possible, stop/start/re-read etc. But it is not working. When whenever I try to start the server after stopping, I am hearing a warning sound typical in windows. When I perform the server diagnostics in FLEXLM, I am seeing error message such as "Cannot connect to license server", ... I will try to determine what the problem is..."telnet" port (23) on node XXXX does not respond"
I would appreciate a solution to this.
Thanks a bunch.
