Network security: Restrict NTLM: Add server exceptions in this domain

Network security: Restrict NTLM: Add server exceptions in this domain

This policy setting allows you to create an exception list of servers in this domain to which clients are allowed to use NTLM pass-through authentication if the "Network Security: Restrict NTLM: Deny NTLM authentication in this domain" is set.

If you configure this policy setting, you can define a list of servers in this domain to which clients are allowed to use NTLM authentication.

If you do not configure this policy setting, no exceptions will be applied.

The naming format for servers on this exception list is the fully qualified domain name (FQDN) or NetBIOS server name used by the calling application listed one per line. A single asterisk (*) can be used at the beginning or end of the string as a wildcard character.
