CAUSE:
This problem may occur when all of the following conditions are true:
• You set the Network security: LAN Manager authentication level policy to Send NTLMv2 response only\refuse LM & NTLM.
• You set the Network security: Minimum session security for NTLM SSP based (including secure RPC) clients policy to Require NTLMv2 session security.
• You set the Network security: Minimum session security for NTLM SSP based (including secure RPC) servers policy to Require NTLMv2 session security.
This problem may also occur if you apply a high-security domain policy template because the following policy settings may be enabled by the high-security domain policy template:
• Network security: Minimum session security for NTLM SSP based (including secure RPC) clients
• Network security: Minimum session security for NTLM SSP based (including secure RPC) servers.
