I have a number of web applications using DTC's - but depending on the user,
the message
error '8002801d' Library not registered.
/.../_ScriptLibrary/pm.asp, line 192

this line is always after the CreateObject('DERuntime.DERuntime')

Yet if I use the Web Permissions... dialog in interdev, I can allow myself
to see the site correctly.

WHY??? Which security permissions should be set and where (DCOM/Registry/IIS/Web
Permissions/Network).
