I have installed the Ru8 for Exch2k7 Sp3 on my Clustered Exchange enviroment.
I first installed it on my CAS servers and than installed it on my inactive MTA node.
After the installation on the inactive node this server a mesage diplayed it needed to reboot.
Checking the exchange version I found that my CAS server had nicely been upgraded
Server AdminVersion ExchangeVersion
------ ------------ ---------------
mbx Version 8.3 (Build 83.6) 8.3.264.0
ENODC1 Version 8.3 (Build 83.6) 8.3.279.3
ENODC2 Version 8.3 (Build 83.6) 8.3.279.3
after that I faild over my Cluster and upgraded the last node.
This ran without but it did not ask for the expected reboot.
I checked the services and saw that none of the exchange services where started.
I than rebooted the server and after that all services came up again.
I chscked all functions for exchange and all are working as expected.
Strange thing is that when I checked the version again, the MBX still showed the old version....
Is there some step I missed.
I know that for SP1 and two you needed to give the axtra command "setup.com /upgradecms"
but this is not available for this rollup
