SUMMARY
Event ID: 4126
Source: Application Center
Description: Single-host port rules not supported for NLB
Event Type: Error
Single-host port rules are not supported for network load balancing (NLB). Remove all existing single-host port rules manually on the member by using the
Port Rules tab on the
Network Load Balancing property sheets for the network adapters.
Meaning: Single-host port rules are not supported in managed-network load balancing mode. Remove all existing single-host port rules manually by using the NLB configuration dialog box.
Effect: Application Center management of NLB will not work properly until this change is made. (You can also use a third-party load balancing solution.)
Port rules: The port rules conflict with those required by Application Center. To remove the port rules:
- Open the Network and Dial-up Connections utility.
- Select Local Area Connection and open its property sheets.
- Select Network Load Balancing from the list of services and protocols and open its property sheets.
- Select the Port Rules property sheet.
- Manually configure the settings.
The correct settings are:Port range: 0-65536
Protocols: Both
Affinity: Single
Load weight: 50. (You must clear the Equal check box before you can change this value.)
Equal: selected
Multiple hosts: selected
