SYMPTOMS
A TCP/IP application running on one of the cluster hosts does not appear to work correctly when running Windows NT Load Balancing Service (WLBS). This application is not being load balanced.



CAUSE
This problem may occur because one or more of the application's ports are inadvertently being load balanced. If you create a port rule with a very large port range, you may inadvertently load balance ports for other applications



RESOLUTION
To work around this problem, be sure that the port rules handle ports only for the intended applications.
