[Samba] logon scripts no longer run with p-node netbios type 2

[Chris]

For several days (at least 4) after using DHCP to switch the NetBIOS 
node type from h-node (8) to p-node (2) the systems have worked fine 
(the lease time is only three hours so everyone was affected reasonably 
early).

This morning, however, the logon scripts would not run until I changed 
the node-type back to h-node.

I have found some information regarding timing issues with VPN's but 
this is plain old local logins (server has gigbit nics, going through a 
gigbit switch, clients have 100baseT).

There was one change but I can't really test that until tonight: Samba 
was rebuilt with the hide-special-files patch - 
https://bugzilla.samba.org/show_bug.cgi?id=2514 , which doesn't seem 
like it should cause a problem.

Any other ideas?

Thanks.

Chris
