The Negotiated SMB version would be the highest version supported by both Client and the Storage controller. Some clients may not support some protocols, and in some storage controllers some protocols are disabled by default.
I know I'm late to the party here, but I am also seeking a solution to allow the Macs at my studio to search the NetApp SAN. I tried going to both links you seggested but neither is valid anymore. Any help would be greatly appreciated.
Thanks for the quick responce, I appreciate it. Perhaps I was less than clear. I don't have a problem mounting and accessing the various SAN shares, that works fine. The problem is when users are trying to search for a specific file on the SAN they can't search for it. We've got many thousands of files, and it would be huge for us to be able to search for files again.
