Hi Pedro, I had a problem that looked the same when I added WSE to my .NET configuration. In that case it was caused by WS-Routing and was solved by turning off the MustUnderstand flag on PATH, like this in your .NET client code:
service.RequestSoapContext.Path.MustUnderstand = false; Note, this solution is from the Axis Wiki section on Interoperability with .NET. However, this could be caused by other such config problems and you need to look at what is happening on the wire or Server to tell more. I'd use tcpmon and server logging to track it down. --Sergeant ====================== >From Pedro: ====================== Hi, I created a WS with Axis and a .NET client and all works fine in my development machine. But, when I try to run the .NET client in another machine (both machines running Windows XP Pro) I get the exception: "The underlying connection was closed. Unable to connect to the remote server.". I know this is not an Axis issue, but seems a simple security problem in the client, that I imagine a lot of you have already encountered and solved. Thank you very much, Pedro Maia
