In your c:\Program Files\Solid Edge ST8\Preferences folder, you will see a file called selicense.dat. That is the license file... If you open it with Notepad, it should contain the information for your server as shown below:
SERVER yourservername SE_HWKEY_ID=nnnnn 27001 VENDOR selmd USE_SERVER
"yourservername" is the name of the license server. "nnnnn" is your hardware key number but I do not believe it is needed. "27001" is the port number and is the default delivered with the license server/file, but could be changed by the license admin if you have pultiple products using flexLM.
