Windows XP does not allow multiple users to log on to the Remote Desktop at the same time. When another user remotely logs on to Windows XP, the user currently logged on to the host will automatically exit. However, Windows XP SP2 provides the allow connection session concurrency function, which allows multiple users to log on simultaneously through remote desktop. However, this feature is disabled by default, you must modify the Registry to enable this function.
Open the Registry Editor, expand the branch "HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Control \ Terminal Server \ licensing core", go to the right window, and create a DWORD-type subkey in it, name the key "enableconcurrentsessions" and set the key value to "1" to enable multi-user logon.
