To connect to XP + SP2 from PE you need to disable some of the security features added by SP2. Run the following reg file on the XP + SP2 machine to which you are trying to connect:
Windows Registry Editor Version 5.00
You will need to use the target computer name as part of the /user parameter for a workgroup connection.
