Hi Rom and Jord -
I did it! :-)
Remembering the DOS time is funny.

The results may not be easy for you because the text is in German, e.g. the special letter ue (in German ü) is not printed. I don't think that this will trouble you because the structure of the results seems to be clear.

Hope that the results can lead you to the solution.
Regards Udo

Is 'Mitglieder' the one that cannot connect to the BOINC?

Hi Rom -
user 'Udo' is having the problem. He is no admin!
'Udo Hübner' is admin and has no problems.

One thing I forgot to mention is that I had installed the 64 bit 7.1.1 version of BOINC after I read of the changes that it included.

I'm running Windows 7 Professional 64 bit so it was easy enough to add my limited user to the boinc_users local group.

UDO - I just wanted to be clear, you have a limited user "Udo" and an Admin account "Udo Hubner". I'm wandering if having both accounts containing "UDO" might be causing an issue. It would be easy to check by creating a new limited user account, you could call it "ACE", and then adding that new account to the boinc_users local group.

Hi Dirk -
sorry for the delay because of holidays.
Your two hints seemed to be reasonable.
I installed 7.1.3 (which is now the preliminary version) without success.
After this manipulation I created the user ACE. Also without success.
Thus, I have to wait until somebody finds the fault.
Regards Udo
