File transfer with XP wizard over LAN

We just purchased a new computer and want to transfer files/settings form old to new. I set up a password on my new computer, and connected to my network (5 computers). I went to my workgroup, and I can see my new and old computer. The file transfer goes smoothly using the xp disk, and then the old computer that i am transfering FROM throws up a password box, and says “Enter password for your new computer”. It wont take the password I set up as administrator on windows xp on the new computer, and boots me out, and says file wizard not complete. no files transferred. I NEED HELP. PLEASE. I need to transfer the data. Am I missing something? Can some one assist please?
