I have a user that is using Outlook (Office XP version) and cannot send
email through an external Internet email server. He is using the same
settings as everyone else on the network and they are all working. His
email account settings are ok and he can log in to his email via a web
browser.

I took his settings to a computer that was working but after I put his
account on their computer now that user is failing (drat!).

The one clue I have found is in the 'Small Business Server
Administrator Console', (yes they are configured to go through ISA
server). For the users that fail they show no User and their Client
Computer is listed as an ip Address rather than a machine name such as
WKSTN12.

Help!!!

I don't know what was causing it but I fixed it myself. I removed each
computer from the domain, uninstalled MS Proxy, joined the domain and
reinstalled proxy.
