Re: Logon failure on disabled Administrator account



A workaround is to remote into your "home" system (that has the allowed IP
address), and then connect from there to the customer.

Steve:

That works if I only remote in from known locations. But if f I'm out at
another client's and this one calls in, I'm stuck. I may start adding
select
clients IPs though. That would allow finer grain control and only force me
to
reconfigure the firewall if I'm somewhere else.

Thanks.

If you have ISA 2004 installed you can use that to allow in only the

The attempts to connect are coming in over port 3389, the terminal
services
port. I use it for remote administration.

Isn't it considered good security practice to disable Administrator and
use
another account for administrator tasks. Doesn't Microsoft recommend
it? I
know many others do.

Don't disable the administrator account. Frankly, in SBS, I've had
problems
even *renaming* it.; there are plenty of services and inner workings
that
expect it to be there & expect it to be called administrator
(particularly
your monitoring stuff). Just set an impossible-to-guess password on
it.

Where are the brute force attacks coming from, and if this is outside
your
network, over what ports are they coming in - and what kind of
firewall
protection do you have?
