When I am at home I connect to the internet without a proxy.
At the office, they say, because of security , I must surf through a proxy server.
I need to change the network proxy server settings in IE. from using at work to not using at home.
All the programs I use then work, they seem to pick up these settings from IE..

However.
My nettalk app calls some webservices.
It work well at home, but when I run from the office, I get proxy server errors.
1. How can I detect that I need to use a proxy server, and what settings
2. How do I tell nettalk to use the proxy settings

See the NetDemo app, WebClient procedure.
There are proxy settings on the Address tab and Authentication tab.

So there you go, you need to enter authentication data. See the NetDemo example.
We don't support NTLM authentication, but most Proxies support Digest authentication.
Which NetTalk build are you using?

cheers
