CAS question   
i've been reading that cas servers are made highly available via NLB and HT's 
are made redundant by adding more HT's.  that being said, can a NLB clustered 
CAS also run the HT role?  In essence, can the roles live together if I'm 
planning on using NLB?  the idea here would be to minimize the total amount 
of hardware required.

Re: CAS question   
- Sure - they can be on the same server.
- Just make sure you don't NLB port 25 (default Receive Connector) on Hub 
Transport servers.
- The client Recieve Connector (tcp port 587) on the HT server can also be 
load-balanced using NLB.
