Hey Guys, I'm trying to get my MBP to authenticate to my domain controller here at home. Do I still have to disable SMB signing on the domain controller, or was this resolved in tiger? Also, I run a domain controller on this machine and when I do an nslookup for my active directory domain from the mac, it does not resolve; however it is the only dns server that the mac is set up for. It will not resolve host names to the other computers on the network; however I can ping them. Do you think that this is a security issue as well? It's killing me because of course without working dns, I can't BIND to the active directory. Thanks in advance.
