Windows 2003, Exchange 2003, 4-node cluster, 3 active 1 passive.
BAclient 5.3.2.2.
TDP For Exchange NOT installed yet.
 
Have installed the Windows baclient, trying to get a backup of the C: drive and 
system state before we start installing the TDP for Exchange and all the 
appropriate schedulers.
 
On NODE4 (the passive node), got the baclient installed and backed up the C: 
drive.
Then used the cluster admin app to move Exchange resources from one of the 
other nodes to NODE4.
 
Now the Baclient won't open.  Just hangs at the splash screen with msg 
"initializing".
Domain is C:, E;, SYSTEM SERVICES, SYSTEM STATE.
 
A reboot clears things up.  But once the resources get moved back to NODE4, 
same result - GUI hangs.
(And this is the baclient, not the TDP client....)
 
Results are the same whether I have CLUSTERNODE YES in the dsm.opt file or not. 
 (Is CLUSTERNODE YES required for the client instance that is to back up the 
local resources only?)
 
Any hints?  No error messages, eventually have to kill the process with Task 
Manager.
