In the first one we had an NLB Cluster with 2 nodes, each node having one interface on which only the NLB (common) IP address was configureden-USTelligent Evolution Platform Developer Build (Build: 5.6.50428.7875)http://blogs.technet.com/b/netro/archive/2012/01/23/ping-transmit-failed-general-failure-and-general-outgoing-connections-on-a-nlb-cluster-node.aspx#3550254Mon, 04 Feb 2013 16:42:53 GMTd5e57398-b9ef-4490-9955-07cbb4e4a80d:3550254sebash<p>Does your Server have at least one Connected NIC with at least one IP Address that does not have the SkipAsSource flag set? </p> <p>Does your IP Config have a gateway? </p> <p>The error is not specific to NLB Clusters, it is just more common in this scenario since the NLB Cluster IPs are added with this flag set, so there are no connection initiated from this IPs. </p> <p>A TCPIP etl trace might show you the cause of the error.
