Can't Connect to License Server Error
This problem could be caused by the Windows XP firewall software on the license server. Prior to Service Pack 2, the firewall was turned off by default. But after installing Service Pack 2, the firewall is turned on by default. The initial settings of the firewall are set to block the communication between your local client machine and the FLEXlm license server. This means you will not be able to get a license without configuring the firewall on the License Server.
