I have an issue with SMB shares on a Mac OSX.3 server. I have connected it to the active directory and I can authenticate against the Windows credentials which are now available, but the problem is I can't connect to it via a UNC path, just IP. I can connect to '<server ip>share name' fine, but as soon as I put the name in as '<servername>share' or just '<servername>' to look for available shares, I get a "account not authorised to log in from this station" error. I have ensured the mac has a record in our DNS, and when I ping the IP I get a fully qualified name back. The weird thing is our UNIX Samba shares can be accessed this way, and browsing the Windows network UNIX machines appear as icons, but not the macs. Is there a host announcement or service announcement I'm missing?
