SUMMARY
Windows Clustering is dependent upon network communication. The following 1122 and 4201 event success messages are natural occurrences in a clustered environment. These messages occur when one of the nodes is restarted, and then comes back online.

10/2/2000  05:49:47 PM 4   16  1122    ClusSvc N/A The node (re)established communication with cluster node Private or Public Net Card was reconnected since the other node was rebooted and lost communication with the other node. 10/2/2000  05:40:37 PM 4   0   4201    Tcpip   N/A The system detected that network adapter was connected to the network, and has initiated normal operation over the network adapter. The network is now fully functional.



MORE INFORMATION
If this behavior repeatedly occurs and no restart has occurred on the other node, it is an indication that the network is failing which could lead to cluster failure.

When the network is in a functional state, Windows Clustering cannot re-establish communication. An event may be using the Media Sensing feature and never be completely unsuccessful. This behavior may occur if the NIC Teaming feature is wrongly configured on either node.

You can disable the NIC Teaming feature and observe if the problem is resolved. This behavior, however, may also be an indication of a faulty network adapter.
