I'm installing an ASP.Net 2.0 web applications project (WAP) application on
a production server (Win 2003). I've installed it on XP test machines before
and it runs fine. On my production machine I get this error (full error
screen below) when I attempt to visit the start page. The type
("MyCo.Ing.MyAppRoleProvider") is in my main assembly in the \bin folder.
Can anyone tell me what I'm doing wrong or what I should check? TIA.

Server Error in '/MyApp' Application.
