Thanks for the replies as this has been very frustrating. Yahoo Messenger itself has four different ways to connect: "no proxies" "firewall with proxies" "use proxies" "no network detection." I have tried all four separately, on different days - many, many times. None of them work.
I guess what using "use proxies" I really don't know what to enter. I've snooped around and I believe we have HTTP proxy going on here as opposed to SOCKS. I don't know the difference, I'm just guessing from having gone through the Windows XP Control Panels and looking at the firewall settings.
When I enter a proxy setting - I really don't know what I'm supposed to enter. There is a place for server name and server port. I've entered all the different Yahoo Messenger servers & ports, and I tried entering what I believe to be our server information here where I work.
When I had Trillian downloaded, which I downloaded last week, I know I had the most recent version from their website. I opened the console to see what was happening when it tried to connect to Yahoo, and I got:
16:02] *** Error while connecting (Error Code: 0). Disconnecting.
[16:03] *** Connecting to Yahoo! as "gingerwatch", attempt 9.
[16:03] *** Error while connecting (Error Code: 0). Disconnecting.
There was a whole string of attempts, beginning with 1, 2, 3 and so on.
I've also tried monitering the attempts by going to start - run - type in "cmd" and type "netstat." That will tell you a bunch of stuff too, but I don't know what any of it means.
As far as Trillian, LOTS of people cannot connect to Yahoo - there are lots of posts at Trillian, and if you look at the dates they are from the past couple weeks/months:
Do either of you know what this Windows box might be, that asks for a username and password and has a logo of two keys on it? This occurs SOME of the times that I attempt to launch Yahoo. It has our company server name on the top of it.
