Access denied to DCOM ASP.net WinXP sp2

[DotNetJunkies User]

Hi,

I have a web application that accesses a DCOM. Every thing works fine on Windows XP sp1 but when I installed service pack 2 I got an access denied when the application tried to create an instance to the DCOM.

C# code where I get the access is denied occurred.
OPCserverObj = Activator.CreateInstance(typeofOPCserver);

Does anybody have an idée on how to solve this problem?

Many Thanks
Dan

Have you reviewed the info about SP2 and DCOM?

"The DCOM infrastructure also has additional access control restrictions to
reduce the risk of a successful network attack."
