Http error 404 on XML Spy

Hi,

Iam new to both XMLSPY and Tamino Server…I downloaded tamino 4.1.4 and xmlspy 5 enterprise version.Tamino worked fine with all the examples(Loading, xquery), manager and others…Now iam trying to open tamino from xmlspy.

I tried to List Schemas from Convert|Tamino|List Schema…ServerName as server.mydomain.net (which i found in the welcome/index.html page at Server Info.)It says HTTP error 404. What am i supposed to give at Server Name…

Can anyone please help me out…I would really appreciate it.
Thanks
Vidya
