dcom

I'm working on a DCOM application with the server and client on two machines, both of which are running WinXP with Service Pack 2. On both machines, I'm logged in with the same username and password.

When the client on one machine calls CoCreateInstanceEx, asking the other machine to start up the server application, it returns E_ACCESSDENIED.

I tried going into the server app's component properties in dcomcnfg and giving full permisions to everyone for everything, but that didn't help.

What do I need to do to allow this call to succeed?

Update: When the server app is running on a Windows 2000 box, I do not get this error; CoCreateInstanceEx returns S_OK.
