SQLENT server-client connection problem

Hi

I have SQLENT version of SQL server, i made virtual machine and on that i have Windows 2003 Server Enterprise Edtition. As u know this SQL server instalation in in 2 parts, server and client. So Server i installed on virtual machine, and it's running perfectly, but client is installed on computer (i'm using Windows XP professional there) and problem is that i can't start SQL server, i can't connect client to server. Usualy i get error message like: "The user is not associaed with trusted SQL server connection, error : 18452" I even made a new login name in virutal's machine SQL server, but doesen't work... Domain name is same on both, SQL Browser is running, TCP/IP also...
I'd apprechiate any help ;)
Thanx
