Good morning.  Can you please provide me with a few details for further clarity?  

• Are you seeing any errors due to this change?  If so, can you please provide the error?
• Is this file server used as a MediaAgent also?  Is this password being used to provide shared access to mount paths?

@Robinson , you can use the Account Management option here:

This will allow you to update any utilized credential in the CommCell.
