Files deleted from Home Directory

WinNT 4 Network. Workstations= Win9x, WinME WinXP Pro. Roaming Profiles are used. 1000 users logging on to 300 computers. School Enviroinment.
When users log off from WinXP Pro their files are being deleted from Home Directory.
I have read Q182079 that this can be caused by using Roaming profiles and Home Directory in the same path. Microsoft recommend creating a profile folder within the home directory. This then causes all files and folders to be COPIED to the profile directory. (Effectively doubling up on used space). Is there any other “simple” solution to this problem? With laptops now being supplied with WinXP Pro this is becoming more of a problem.
Any help will be appreciated!!!!!!
