Change TSM client password on cluster

Or when there are more than one scheduler services.

On the active node, open command prompt
>dsmc -optfile="the opt file that you want to change"
>q se
>set password

Failover to second node, do the same.

Replacing a cert without losing existing cert in IIS

http://support.microsoft.com/kb/295281
