I have a couple of queries on NLB for IIS web farm,as stated below :
1. Assuming Windows based NLB service is used to set up a Web Farm, if a Server node is set to drain out ( with node affinity configured) , will it still continue to service requests from the same user? What I would like to know is, whether the postback
requests will still be serviced by the same server node or will these requests be directed to a different active node?
2. Secondly, assuming F5 Load Balancer is used to load balance a Web Farm, how would it affect the node which was set to Drain out (by setting the Pool member's State property to a value "Only persisitent or active connections allowed" ). Can we be assured
that postback requests will still continue to be served by the drained out node?
Any help would be true appreciated.

When you issue a drainstop command on an NLB cluster, the node will conitue to service the active requests on the node. Once the current requests have been completed. The node will be removed from the cluster. So the state of the active connections in maintained.
