Recently added a first Vista ultimate pc to SBS2003R32 managed server/domain.
All works well on this machine, except for outlook.

Initially outlook worked OK and initial synchronisation of addressbook and
email was OK,
After a few hours/days of use, we get the error that outlook can not connect
to the exchange server 0x8004011D, and after a lot of trying, also 0x80040115

I installed the SBS2003/Vista compatibility patches

I also tried the netsh advfirewall solution. After reboot outlook worked.
After new reboot: connection lost again. (and now also the 0x80040115 message)

Please help, because I've tried so many things, I can't list them all anymore.

I've I'd known that apparantly Vista is not made to run on SBS2003, I'd put
a veto on Vista.

Thanks in advance,

Christof
