General question. When my tech turns Smb off, she changes two group policy settings. For domain member and Microsoft server, disable Smb signing for both. Do I also disable Microsoft client?

Thanks

You are trading security for a small increase in speed. Signing is only enabled for Domain Controllers by default. This ensures that the clients get the correct group policy without a man in the middle attack.

If the server is not signed then the clients must also be set to signing not required or they will not update group policy.

This can be set via group policy.   Please reference this technet document for details: http://blogs.technet.com/b/josebda/archive/2010/12/01/the-basics-of-smb-signing-covering-both-smb1-and-smb2.aspx
