This document will walk you through on configuring your machine so that it can be scanned while it is part of a workgroup and not in a domain.
Although you have the correct credentials, Protect fails to scan a machine that is not part of a domain. Errors include 451 The specified user account requires administrative rights to the target machine. or 452 Unable to connect to the remote machine or 5: Access is Denied.
Scanning Machines in a Workgroup
- If you are not using the built-in Administrator account on the remote machines (and using that account is NOT recommended), you must disable User Account Control (UAC) remote restrictions on the machines. To do this:
- Click Start, click Run, type regedit, and then press Enter.
- Locate and then click the following registry subkey: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System
- On the Edit menu, point to New, and then click DWORD Value.
- Type LocalAccountTokenFilterPolicy and then press Enter.
- Right-click LocalAccountTokenFilterPolicy and then click OK.
- In the Value data box, type 1, and then click OK.
- Exit Registry Editor.
In some instances, exporting/importing this registry key will not correctly fix the issue. If you imported this key via a .reg file, and you continue getting access denied messages, try deleting the registry value and manually entering it using the steps above.
