I am having a simple webservice running in my local system, hosted in IIS 6.0. This webservice is accessible from any other system (within LAN and Internet) and everything works fine as long as the number of systems accessing my webservice is very much limited. Whereas, if more number of users (say 500) are concurrently trying to access my webservice, an exception is thrown saying 'Server is busy'. When i browsed in net, i found that IIS can handle only 100-150 web requests concurrently.

What should i do to make my webservice accessible from more than 500 users, concurrently?

Thanks in advance.
