Isolation: Proxy help!

Hi all, in the last days, after the Nimda infection, the company proxies were changed. I can still read/send email from/to this mailing, but my Rebol (and the Opera browser too) can't reach the web while M$ IE can. I changed the proxy configuration both in Rebol (2 proxies * 4 proxy type = 8 configuration) and Opera without success. Rebol simply delays trying to go outside and puts a "Cant' connect" on the desktop while Opera says: The proxy server requested a login authentication method that is not supported." with the first proxy and asks for user/password with the second. I gave my user/password and the user/pass requester pops up again. Knowing my company policies they are sure using some M$ $tuff, as usual (and this is confirmed by the working IE). I have no chance to test my reblets. Anyone knows something about proxies?

The are probably using the NTLM authentication method. You can test this by telnetting to the proxy and attempting a GET. The result will list the authentication method being used. If it's NTLM that's the problem. NTLM is a Microsoft specific method. For details on the protocol see: http://www.innovation.ch/java/ntlm.html There is a product you can use that tunnels through NTLM proxies. It requires you to run an additional client on your machine. You can get it at: http://www.htthost.com/ Implementing NTLM authentication would be an interesting exercise for Rebol and the first link above should help towards that.
