I don't think so. I'm only seeing this on our Citrix server, which is
for remote access. The server has a different name inside the network as
well. One showed up as Del Rio Video, but we don't have a client with
that name. Another showed up as ABM_Logistic, with the workstation name
ABMHKRF_FTP, which seems to be a shipper in Hong Kong that doesn't have
a web site I can find.

Someone who set their home machine to their home network, brings machine
in,
plugs into your network and tries to sign on with home network
credentials?

I'm seeing odd entries in my security logs. What is showing up are login
attempts to accounts that don't exist and as a domain that isn't ours.

An example is this:
Logon Failure:
Reason: Unknown Username or password
User Name:Christian
Domain:AMITECH
Logon Type 3
Logon Process NtLmSsp
Authentication Package NTLM
Workstation Name: AMITECH

None of the accounts are valid, a few tried to log on as administrator,
but
I had already renamed that account and set the password to a 16
character
random password. I had also set RestrictAnonymous to 2.

I have problems seeing these as serious hack attempts, but they are
annoying
me, and are a bit odd. This is a 2000 SP4 box. I'm current on Windows
security patches.

Should I not worry about these, or is there a way to stop it? I'm also
interested in what causes this, if these may be zombie systems, etc.

Thanks
