Greg,

My initial guess is that you should not mess up his processing as long
as he is making all of his component calls on the default interface of
the component in question. I reckon you could create a com+ app, drop
the component into the com+ app. You may need to restart IIS (from the
cmd prompt use "iisreset") just to ensure that it has released the DLL.

If you want to perform remote connections the above is the simplest
approach.

..hope this helps..

Regards

PAK

PAK, this is what I typically do (COM+ then export the Proxy).  The case
here involves another developer who installed the DLL on the server and
is using it from ASP without COM+.  I now need to use the same DLL
remotely
and I do not want to 'disturb' his processing.

I am looking for alternatives as it may be a hard sell to the business
owner
of the server to use COM+ simply for this reason (not for transactions
or
other COM+ services).
