OK, I'm at a loss on this one and hopefully *someone* can lead me in the
right direction on this. We have been running ZfD 6.5 SP1 for a little
while now, and we've found that at our schools that have WinXP SP2
installed certain websites will not function if Group Policies are in
place on a Guest/User account. If we change the DLU policy to make the
user a member of Power Users/Admin, or disable Group Policies completely
then things work correctly. The sites that definitely display the problem
are yahoo/alta vista (the main page loads fine, but once you try
searching it hangs) and windowsupdate.com (hangs right away).

Has anyone else seen this? Please? I'm pulling my hair out...
