I have a similar problem as I changed the pw for the user running the sqlagent service (our network admin left the organization so we had to change the pw's for all domain admin. users) and the service states that it is starting....

I tried starting the sqlagent from the command prompt and get no return and a blank .txt file as output. Nothing in the application log of the event viewer or the SQLAGENT.OUT.

I believe this is related to the mail profile for the user because when I log on to the server as the user who runs the sqlagent service and launch Outlook it hangs as well. Trying to stop the SQL mail service in MMC also hangs.

Any other suggestions?

This is a production server so I can't boot during business hours.

Thanks.
