COM components normally required registration on the machines on which they
are intended to run. However, if your client machines are all running
Windows XP, you may be able to take advantage of registration-free COM
(although I haven't seen any explicit mention of whether this should work
from an IE-hosted winforms control). See
http://msdn.microsoft.com/msdnmag/issues/05/04/RegFreeCOM/default.aspx and
http://msdn.microsoft.com/msdnmag/issues/05/04/RegFreeCOM/default.aspx?side=true
for details.
If you need to support clients running earlier Windows versions, you might
be able to take advantage of the technique described at
http://blogs.msdn.com/mikhailarkhipov/archive/2005/04/01/404433.aspx.
However, for a "small intranet application", I'm guessing that installing
and registering the target COM component on the client machines would
probably be a simpler approach overall...
