SAPGUI Error – ERROR:Service ‘?’ unknown

Sometimes when I try to login to the SAP system, the GUI pop up the error message “Error: Service ‘?’ unknown”. I confused by this error message but don’t know how to fix this.
I got some time today and fortunately found the route of the problem.
1. First copy the saplogon.ini file to below folder:
C:WINNT or C:Windows for Windows XP
C:users<user profile>AppDataLocalVirtual StoreWindows for Vista and windows 7. For more information, please check SAP note: 1031740 for detail information.
2. If you open SAP GUI and it pop up above error message immediately, you need to check whether the connection is configured using load-balance way. If yes, please check file named ‘services’ under folder ‘C:WINNTsystem32driversetc’.
You need to maintain the entry like below:
sapmsABC 3600/tcp
The first value is also configured in the saplogon.ini and standards for port used by the message server.
3. It should be working by now. If there are still some errors, it should related to other issues. Please also check file named ‘hosts’ to check whether the IP and the host named are mapped.
