| Source | ClusSvc |
| Description | Cluster service is shutting down because the membership engine detected a membership event while trying to join the server cluster. Shutting down is the normal response to this type of event. Cluster service will restart per the Service Managers recovery actions. |
| Event Information | According to Microsoft: 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. RESOLUTION: To work around this problem, remove the NTLM version 2 (NTLMv2) requirement from the security policies.To do this, follow these steps: 1. Click Start, point to Administrative Tools, and then click Domain Security Policy. 2. Expand the Local Policies subtree, and then click Security Options. 3. Double-click Network security: Minimum session security for NTLM SSP based (including secure RPC) clients. 4. Click to clear the Require NTLMv2 session security check box, and then click OK. 5. Double-click Network security: Minimum session security for NTLM SSP based (including secure RPC) servers. 6. Click to clear the Require NTLMv2 session security check box, and then click OK. |
