Security problem with Com+ Component

Hi!

I imported a new COM+ Component that was working in 2000 server + IIS and I

putt it to a 2003 server for work with the web that i mount in the IIS too.

It´s impossible view the website in local or from internet... it say that i

haver a problem with the security of the com+. I read that in 2003 the

security in the Com+ is more hard than 2000 server and I´m sure that the

problem is it but I can´t find the solution...

Any solution or idea?

Thanks a lot.
