My Web Service is built in VS 2005 (.NET 2.0), and it runs on my workstation. It also implements WSE 3.0, but I am not running it as self-hosted I am hosting it through IIS.
On the same switch, I have a lap top that runs a client application built in VS 2003 (.NET 1.1) that calls my Web Service. The client is able to connect and make calls to my Web Service with no problems.
However, I have a different workstation on the same switch that has a VS 2005 (.NET 2.0) client application whose connection to my web service is unreliable. When this client is able to connect and call the Web Service the responses are unbelievably slow. (Slow as in 9 minutes to make 1000 calls versus 5 seconds to make 100 calls by the lap top application mentioned earlier) Sometimes, the client makes a Web Service call and gets the following exception:
The request failed with HTTP status 407: Proxy Authentication Required (The ISA Server requires authorization to fulfill the request. Access to the Web Proxy service is denied. ).
How is this possible if two minutes prior the client was able to talk to the Server? Also, why would the connection responses be so slow for the .NET 2.0 client and quick for the .NET 1.1 client?
In IIS I have "Allow Anonymous Access" selected and none of the Authentication options are set. In the web.config file of the Web Service, there is the following as well:
"<authentication mode="None"/>".
Any answer to these issues would be greatly appreciated.
