windows service cannot access a webservice

Question

Hi

We have two servers, both are containing a local application connecting to local web service, applications and services are identical on both servers.

One of the servers work just fine,

The other one is just dead, I have impression the the security configuration are different on those servers.

What prevents an application X from connecting a web-service, given that another application y on the same server can connect to it. and X is a windows service.

What I should check, what is chances?

Thanks

Answer 1

Check if there is any firewall that might need to some ports opened up.

Could there be any kind of AntiVirus or similar set up on one of the servers?

Answer 2

Basic troubleshooting of loosely-coupled applications means independent testing/verification of those services.

Can you access the web service locally through a different application, i.e. a web browser? If you can't reach the service through the browser, then the server configurations (at some level) are not identical.

Only after you're certain the service is reachable should you look into issues with the windows service.
