RDP domain error, if there is no domain. How to fix?

Question

RDP

Expensive time of day.
Tell me, I can not connect to a remote computer via RDP.
I connect both with MacOS (CoRD, MRD, RDC) and with Win xp sp3.
On a remote machine Windows XP SP3 64bit.
I get to the login/password input window. I enter any of the Remote Users - this bug pops up:

You can't select a domain in the account data entry window. Yes, and it's not here. The computer name has a hyphen and numbers, nothing more.
What could be the problem?

Answer 1

.\$usernameDomain "." is the designation for local accounts.
