Hi, I'm attempting to install Exchange 2007 Sp1 on a two node SCC cluster. I run the update on the passive node first as per:- http://technet.microsoft.com/en-us/library/bb691226.aspx Go to upgrade the CMS by using the upgradecms switch and it fails. Any ideas....error information from Setuplogs is not great. Appreciated

This happens with me but in my case i was running command setup /upgradecms from the Exchange Management shell prompt. When i run it from the cmd , it went fine...

please post the ExchangeSetupLog errors ... they are of a great help.
