Fix Recommendation

Configure the policy value for Computer Configuration >> Windows Settings >> Security Settings >> Local Policies >> User Rights Assignment >> "Deny access to this computer from the network" to include the following:

Domain Systems Only:
Enterprise Admins group
Domain Admins group
"Local account and member of Administrators group" or "Local account" (see Note below)

All Systems:
Guests group

Note: Windows Server 2012 R2 added new built-in security groups, "Local account" and "Local account and member of Administrators group". "Local account" is more restrictive but may cause issues on servers such as systems that provide Failover Clustering.
Microsoft Security Advisory Patch 2871997 adds the new security groups to Windows Server 2012.
