Block NTLM Server Exception List

This policy setting determines if NTLM can be used to access specified servers. If you enable this policy setting (valid only if NTLM (LM, NTLM, NTLMv2) is blocked), NTLM can be used to access servers specified. Please enter the desired servers (DNS name, IP address or NetBIOS name) in the edit box, one server name per line. If you disable or do not configure this policy setting, the NTLM access to servers will be determined by other settings.
