I've installed AdminStudio 8.5 and when I try to run it, it wants me to authenticate to my Zenworks (ZCM 10) server. No matter how I type in the url, I get a login failed error.

After digging through the documentation, I saw a line that says that if you want to use the AdminStudio Zenworks edition, your Zenworks server must be on ports 80 and 443. Well, my server is on port 883.

Am I screwed and can't use AdminStudio, or is there a workaround somewhere. If not, I suppose I could do some moving around and I could move my Zen server to port 80, but how do I do that?
