Hi,

I'm trying install version 6.10.18 on Windows Server 2003 for Small Business Server SP2. I get the error message "Failed to add user to the 'boinc_admins' group (Administrator)".

I have tried to run the install procedure using various different permissions (I am logged in as Administrator but I tried that anyways...) - all to no avail.

Any suggestions as to what the problem may be or what I might try as a workaround?

Thanks in advance!

If that's a domain controller server, BOINC 6 (none of them so far) can not be installed on it. You will need to revert back to 5.10.45 (32bit version) or 5.10.45 (64bit version) for now.

BOINC 6 uses limited user accounts on the Local Account basis, whereas the domain controller uses Global Accounts. A fix for this is expected in a future version of BOINC 6, when it will be using a different installer that can add the correct accounts.

If that isn't a domain controller, did you follow the advice to reboot at the end of installing BOINC? Windows needs to finalize the making and using of the accounts during a reboot.

Yes, Small Business Server is always configured as a Domain Controller - I've set up several of them.

Thought to have read a few times how some managed to install BOINC 6 on a DC, with some hands on. At any rate, here's a manual a WCG contributor compiled how to install 6.2.28 on a Domain Server

That post specifically says

The server may be a domain member (but not a domain controller!).

It's the word controller which matters here.

OK, guilty of speed-reading as charged.

But you did mention a DC in the first sentence, and then provided a link....

And this thread specifically mentions Small Business in the thread title, which as previously mentioned is always a DC.
