As part of the installation process for a MOM Management Server you specify the MOM Management Server Action Account or "MSA Account" as it's otherwise known.

If you need to change this account, simply use the "SetActionAccount.exe" command line utility which by default is kept in the "<drive>:\Program Files\Microsoft Operations Manager 2005" directory.

Typing "setactionaccount.exe /?" gives the usage information below:

Usage:
SetActionAccount.exe <configname> <options>
-query Returns the current Action Account settings
-set domain username Sets the action account, setting it to the given account. Use the machine name for local accounts.

For example, if you want to see what account is set for a Management Group called "Group1" you would use the following command:

setactionaccount.exe Group1 -query
