AD/OD integration problem, at sharepoint section

I have been using the tutorial on AD/OD integration from this website and I have run into a problem, my problem occurs when I try to access the newly created share point from a windows machine. I checked the kerberos config and the smb config, they both appear to be all right. Network set up is 2 AD domain controllers and the OSX 10.4.9 server that is running Open Directory (this is the same server as the dirhost, according to the instructions 10.4 is able to do both. Also I am new to Open Directory, i have searched the internet and thsi forum for a similar question and found minimal results, if anyone can point me in the right direction or send me a link to a probabe solution it would be greatly appreciated, if any more information is needed I will give what I can.
