2. On the Server Administration tab, under License Server, click Stop. (Click Yes when prompted for confirmation and OK to complete stopping the license server.)
3. Under License Information, click Modify.
4. Under Server Type, select the server arrangement for your network (Single or Triad) and then click Next.
5. Under Server Information:
   1. Select A firewall is in use on this server.
   2. Port Number and Vendor Daemon Port Number should contain the port numbers specified for the Windows Firewall (for details, see Modifying License Manager Computer Ports for Windows Firewall).
   3. Click Next and then click Finish.
