[Samba] Joining XP clients to a Samba PDC

[Chuck Theobald]

Hi Andrew,

I ran into a couple of XP issues when trying to join my Totalnet Advanced 
Server (TAS) domain.  Though not exactly Samba, this was a change on the XP 
end and may help.  I found that I had to change the local security policy 
such that "Domain member: Digitally encrypt or sign secure channel data 
(always)" had to be disabled.  A reboot afterwards is needed.  This is 
found under Control Panel -> Performance and Maintenance -> Administrative 
Tools -> Local Security Policy -> Security Settings -> Local Policies -> 
Security Options.  I also had to disable the Internet Connection Firewall, 
at least with non-SP2.  SP2 will generally prompt you as to whether to 
allow programs to get through the firewall.  If you are not using domain 
membership, this may not apply, but it would be good to check into the 
firewall angle in any case.

Chuck
