Windows 7: Service unknown when using load balancing group
I try to run SAP GUI 7.10 on Windows 7. I use a load balancing group to connect to the server. The direct access to one of our cluster nodes works ok, but when clicking the link to the load balancing group says "load balancing error on logon 88: connection to messaging server not possible (rc=9)" (translated from german).
What is happening here? It works good on Windows XP. Do I have to use another saplogon.ini or something?
Thanks for any help!
