Please help me

Error msg: There was no endpoint listening at http://URL that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details.

My WCF is called in Windows service. While my service hosted in 32 bit functions properly after migration to 64 bit.. It respond to some calls and throws the above error.

Why it respond to some calls and not the other. What should I change to fix it.

Thanks a lot in advance.

Can you publish your WCF binding file here?

As you said your service is load balanced and it responds to some calls and not all..
To find out the faulty node, do the basic sanity check.

1) Make sure that all the nodes of your load balanced environment have the latest service installed and they are all up and running. To check this, browse the service by using node specific URL and not the load balancer URL.
2) Make sure you have the same (correct) web.config on all the nodes attached to the load balancer.
