Hi,
My cluster consist of one exchange box and one failover box.  My exchange box took a dive several days ago.  Now, I only have the secondary node up and running.
My question to you is:

To recover from this:
1.  I went ahead and deployed a new system using the same "failed" exchange server hostname and ip address.  Prior to joining the server to the domain, I went ahead and reset the server object account in AD. 
2.  When I try to install exchange on this server (after ensuring the other server is turned off, since I have to rename the new server to the EVS name and IP address) in disaster recovery mode, I keep getting a prompt to provide a password.  The message that is appearing is: 

"The microsoft exchange messaging and collaboration services component 
 
requires a username, domain, and password for the existing exchange 5.5 
 
installation service account' 

3.  We never had exchange 5.5 in the environment.  I went even so far in ADSI and made sure the attributes that MS says to check that could cause this window to appear - they don't.

4.  In reading the Veritas Cluster Server Implementation Guide for MS Exchange - I'm a bit confused when it sugges to install Exchange server on additional nodes. 

I guess my question to you is - should I be installing Exchange in a "normal" mode or "disasterrecovery" mode?
