Service Account lockout

[kevinrobson]

We use a specific domain Admin account to run all our Backup Exec services (6.11 & 7.3). Recently the account has started locking out and I would like to know why this is happening. I know someone has probably entered the service account with a wrong password but why is it locking out even after the services have failed to start.

I also use a Domain Admin account. I've recently changed the passwords so different domains have different passwords.
Now one domain keeps having its account locked out, when two servers from another domain do 'something' every 15 seconds. These servers have backup exec on them, but have no references to the other domain within backup exec!
