Question : Active Directory users profiles not always mapping correctly

I have a windows 2003 environment with XP users.  I use the active directory users and computers, the profile tab of a user account, to map their personal network drive. (Ex: Connect P: To \\files\users\bob)   This had been working fine for years but with the newest round of computers about every other logon maps a folder short.  \\files\users\bob\ becomes \\files\users\
Which shows all users folders, instead of the correct users folder.  This only maps incorrectly for the newest computers ... all other computers XP/2000 map correctly.  And this only happens about every other time.  It isn't consistent at all.  At first a thought this might be because the new computers are logging on too fast.  Anyways any help on this would be great.

Answer : Active Directory users profiles not always mapping correctly

Disabling the fast logon feature by putting the "Always wait for network...." setting worked for us.
This is in Comptuer Configuration / Administrative Templates / System / Logon.
We also set Comptuer Configuration / Administrative Templates / System / Group Policy
