The SSP Timer Job Distribution List Import Job was not run

I used to get this error very often in Event Log:

The SSP Timer Job Distribution List Import Job was not run.
Reason: Logon failure: unknown user name or bad password

After a quick search in net, I found the resolution for this. It is a simple 3 steps:

Here, "newPassword" is the password which you use it for MOSS account.

1. On the machine where Central Administration resides, execute the following command:

stsadm -o updatefarmcredentials -userlogin "domain user" -password "newPassword"

2. iisreset /noforce (optional)

3. Execute the following command:

stsadm -o updateaccountpassword -userlogin "domain user" -password "newpassword" -noadmin

It solved the problem!
