Still no way to stop multiple logons?

Is there still no solution to this issue in W2K?

With roaming profiles, one needs to trap a duplicate logon before the
profile is downloaded, otherwise profile can get out of sync as follows.

User logs on at A, downloads profile from server
User logs on at B, downloads profile from server
User updates profile at A
User logs off at A, uploading profile to server
User logs off at B, uploading profile to server and regressing changes made
to profile at A

Any ideas anyone?

Thanks
