Can I create a share on a Windows Server Domain Controller for anonymous Mac OS access?

Solution 1:

In order for Anonymous Macs to connect to Windows a local security policy needs to be changed. Run gpedit.msc. Open Local Computer Policy > Windows Settings > Security Settings > Security Options. Scroll down to find "Network access: Let Everyone permissions apply to anonymous users" and enable this setting. Run "gpupdate /force".

Your Macs should be able to connect as Guests.

I've also solved this by creating one user account in the domain like "Updates" and telling everyone the password. Then they can all log in as the "Updates" user and access any share you allow this domain user to access.
