Thanks everyone. Will let you know how it goes. @Robert - yup, I wonder why that is? Kerberos issue? For CAS, I'm planning on removing the servers from the load balancing applicance for a couple of days before patching to minimise any disruption.

Exchange 2010 DAG includes... (4)CAS/HUB VMs and (4)MB VMs, (4)Hyper-V hosts The only issues I have seen... A few Outlook 2007 clients will lose authentication and be prompted for credentials when I reboot a single CAS server. Sometimes I have a Smartphone lose "sync" and the account has to be deleted and re-added on the phone.

Anyone done this yet? My plan was simply to switchover, patch, switchover again, patch, balance the databases. Is it that simple or so I need to do some reading?
