QTP/UFT Support Tip: Most common troubleshooting steps for Licensing issues

Hello everyone,


In scenarios where QTP/UFT displays an error message when either the license server host is not found on the network or an invalid host name is specified.


Please check the following:


  • The license server port number 5093 is used by the UDP protocol when transferring data between the license server and the client. You will need to open this port on any Router or firewall otherwise all communication between the client and the server will be blocked. Also, it needs to be bi-directional, since the client will request the license and the server needs to send it to the client (http://support.openview.hp.com/selfsolve/document/KM175032).



  • Replace the “LSHOST” (if exist) for “LSFORCEHOST” Environment Variable: Start -> Right click My Computer -> Properties -> Advance Tab.


  • Check with your Network Administrator if you are using VPN, if so, it is recommended to install License Server version 8.4, or a later version when one is available, which is provided with the installation DVD of Unified Functional Testing (UFT) 11.50. (http://support.openview.hp.com/selfsolve/document/KM193044).



Hope this helps.
