Only one usage of each socket address

I have a client making web service calls to a NLB cluster. When the cluster
was comprised by two machines everything went fine serving near two hundred
service requests per second.
Now I increased the number of machines in the NLB to four and I started
getting Socket Exceptions related to 'Only one usage of each socket address'.
I already checked the TcpTimedWaitDelay and MaxUserPorts in the registry so I
don't think the problem is related to those settings.
Any idea about what can be happening?

Best regards,
Rodrigo.
