I'm first seeing this problem with Samba-3.0.23d, if you reboot a Windows XP machine after it has run for several days, the initial loading of the roaming profile after the reboot takes extremly long. 11 MB Profile takes 3-4 minutes to load on a Gigabit network. When I then logoff and logon again, the profile loads in a reasonable time. Also rebooting the machine again once you have logged on loads the profile in a reasonably timeframe. It does not seem that Windows 2000 has this problem and that this is soley related to Windows XP. File Transfers to and from the Samba Machine in general works at normal rates.

Before this version, the client was running samba-3.0.14a and did not have this problem.  I have another client running 3.0.22 who does also not have this problem.

The roaming profiles are stored in

/home/username/.winprofile

The permissions of the Homedirectory are

0700
username:Domain Users
