remote usernames are messed up after renaming

Hi NG,

I have a PC with Windows Vista Ultimate. During the installation I
created a user called "Terra" with password "XXX" (not the actual
password XD).

Later I decided that I want to use this Account for something else and
renamed it to "MCE".

Later I decided that I still want a User called "Terra", so I created
one with password "YYY".

Now comes the problem. Local I can use the users:

MCE / XXX
Terra / YYY

But when I try to connect to the PC with Remote Desktop, those users do
not work. Remote desktop only accepts the following combinations:

Terra / XXX
Terra_2 / YYY

so, that's a little bit messed up imho?!
Can I change this behaviour?

Stefan
