Remote access being blocked.

2003 Small Business Server set up as a terminal server.
This connection has been working for months. All of a sudden, unable
to remotely access the server. Had been using Remote Desketop accross
a public IP. Getting the following message in the Event Log:
A Demand Dial connection to the remote interface Small Business
Broadband Connection on port PPPoE4-0 was successfully initiated but
failed to complete successfully because of the following error:
Access was denied because the username and/or password was invalid on
the domain. I've checked and even reset all passwords but continue to
get this message. Attempted to telnet port 3389 from another pc but
can't connect. Shutdown antivirus and disabled all firewalls but
still can't connect. Anyone has any idea what could be causing this
problem.

I have a very similar problem. Ever since MS installed Security Updates on
8/15/2007 I have been unable to use my remote access to my work computer. I
don't get any type error message, it just waits and waits and then returns to
my sign in page.

I am trying to find out if I delete the security updates if it was cause
"more" problems.
