[Samba] Domains and Windows Update

[Adam Williams]

I've got several dozen Windows XP Pro computers in a Samba/Windows 
Domain.  The problem is that with them being in the domain, automatic 
updates does not work on these computers.  I think its because the 
people log into the computers with the default windows domain 
restrictions (you know, can't install anything, can't adjust the time on 
the clock, can't update drivers, etc).  Having staff use IE to go to 
http://windowsupdate.microsoft.com does not work either, due to 
permissions.  Are there any solutions to this so that automatic updates 
can run?
