First of all, I can't believe I'm still posting for SPS2003, but here we go...

Ok, this happened a while ago, I tried to see the settings for a Virtual Server in SharePoint v2 farm and it kept displaying the help window to upgrade a virtual server (it should display the Virtual Server settings because it's already upgraded, or extended).

After some minutes I realized that I could fabricate my url to enter the settings of a Virtual Server this way:

http://server:centraladminport/vssettings.aspx?VirtualServer=http://uriofmyvirtualserver.com

Wish me luck with this messed up farm.
