Over 95% of the dlls that I've tried will work in com+. This has the down side that the component ends up in its own process and each call into the component is cross-process. It makes sense when the component is peripheral to the site operation. I'm not sure I would be comfortable upgrading a component whilst the are still existing sessions in the site. I guess it would be safe if you know exactly how its used. If the component is core to the site then having the site available while upgrading it isn't desirable. In that case one option would be to use high isolation (or a separate application pool IIS 6) instead of a separate COM+ application. The site can be unloaded and/or stopped without affecting any other sites that are still running. -- Anthony Jones - MVP ASP/ASP.NET

Does the component have an installer or have you just copied the dll. Can you create an nearly empty component with no additional dependancies. Does that work? Has the VB runtime been installed? Does it use ADO? if so install the latest MDAC from MS download site. If the dependencies are few what are they? -- Anthony Jones - MVP ASP/ASP.NET

I just copied over the dll;s and started registering it .. additional dependencies are the custom dlls which is written like db connect component,upload component etc., It uses ADO. I used filemon,regmon ... but no indications whatsoever .. To my surprise, I created a near empty component which adds two integers and I called it from .asp page and it works. I am geting little confused noe ;-) whers the problem .. ??

If so download this tool from Microsoft:- http://www.microsoft.com/technet/sysinternals/ProcessesAndThreads/ProcessExplorer.mspx and install it on the working machine. In IIS manager set application protection to high (isolated). This will ensure your web app runs in its own process. Visit the page on the working machine. This will cause the application process to spin up and load all the dlls it needs to do the job. Now use Component Services mmc console click on COM+ Applications in My computer. Change to Status view. You should see a number of App names starting with IIS. One will be IIS-{name of your app}. It will be running and it will have a process ID. Now start the ProcessExplorer app that you down loaded. It will list a set of process 2 or more will be DLLHOST.exe process, one of which will have the process ID noted above. This is Web applications process. Click on the process and make sure the lower pane is in dll view. Now you need to do some spade work check that each dll listed is present on the new machine. -- Anthony Jones - MVP ASP/ASP.NET
