access denied to DCOM, winXP sp2

[Guest]

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?

this happens because on install of sp2 this put a firewall an you cann't
access nothing until you disable this. go to control panel. in security
center you'll find windows firewall. dezactivate this.
cheers

Thanks for the help, I solved it by adding the correct user to have access to
the DCOM.
