i have an win server 2008 r2 and exchange 2010 ru4 installed.
I try to install the sp1 off exchange, but the installation always hang at the prerequis check at hub transport with the error "problem hapend when acces he registry access, this could happend if the remote regisrty service is stopped, or if you have a network problem or NetBios TCP/IP service stopped."
All my services is started and outlook work find so I think my network is good
