We have deployed a Windows Server 2012 in a workgroup (regrettably). We have created users and applied the appropriate share and NTFS permissions. This worked for about a day until we enabled the Guest account. The Guest account is necessary for a piece of antiquated software that cannot be upgraded. When we map drives as a particular user, or any user for that matter even the administrator, we receive access denied messages on folders without the Guest account added to the folder permissions. Share permissions are always set to Everyone Full access.
When we disabled the Guest account begin seeing the following in the Security log. Looks like it is somehow mapping to the Guest account. We tried creating a new domain admin, clearing out Credentials on Windows 7 computer, rebooting, but not luck on XP or 7 computers. Any thoughts.
