Here are some postings about potential managed hosting companies. Please note that I did not participate in this discussion. I am currently in the process of researching and evaluating new potential hosting companies in order to find one that can provide better security configuration and resolve some of the problems mentioned in past articles.
Managed Hosting - Comparison
It is very difficult to find a hosting company that sounds confident in their ability completely secure DCOM based on the applications I am running. I know what the potential settings are but am not sure why setting them a certain way crashes a server. Additionally it is unclear what settings must be left turned on for the applications at the managed hosting companies - most of them don't even know if their applications require DCOM or not.
