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!

    You need to modify the "services" file, add the string like

    sapmsSID 3600/tcp (if your system number are 00).

    On XP location are Drive:\WINDOWS\system32\drivers\etc

    same on Vista, i'm think .... %WINDIR%\System32\Drivers\etc\

    but for edit this file you need to start notepad using Administrative privilegies (not enough only be member of Administrators) -->

    it's example about "hosts" file

    But i do not know how it works on Windows 7 ))

    • Is it ok to deactivate UAC in a company?

      That's something your M$ group must decide.

      It sounds like a good security feature but as we see here it´s a pain in the @$$ for administrators...

      Well - the purpose of it is to disable the ability of malware and virusses spreading around. I consider it as a security breach if a local user is able to simply copy files to the operating systems main directory. A user working with a frontend PC should not have local administrator rights at all; all software requiring this badly designed.

      If you use the SAPGUI installation server you can distribute services, saplogon.ini etc. using the installation server provided service without the need of users having to have local administration rights:

      Note 512040 - Distributing "services", "saplogon.ini", and similar files.

      I just think that "administrators" must learn to do work properly as designed with operating systems without just "copying files around" in system directories (and I don't exclude me in that context).

    what happened then... on my Windows 7 64-Bit both services and saplogon.ini are OK;

    I checked with sysinternal tcpview utility for a proper call to remote_server:3600, which is OK.

    however, I still got RC=9 error, then rc=-12 in the details.

    thank you.
