Customizing user name onto remote desktop

Goodmorning,

i have a pc with xp pro sp2 with all patch to now.

We use this pc for remote connection to remote server, srv w2k3 that respond

to ip 192.168.1.23.

I would obtain that the user name for connection is only preset, by me,

<user name> only. Now i obtain a "192.168.2.23\<user name>".

Is possible to do some?

Thanks
