Did VB 6/.NET interop recently get broken by a Windows update?

Question

Recently a VB 6 application using .NET 1.1/2.0 components stopped working on my companies XP machines. The IT department was installing Windows patches at the time, so I'm wondering if anyone has heard of an update breaking VB 6/.NET interop?

Answer 1

Are you running the COM+ components as proxies against other servers? If so, I've had problems before when installing e.g. SP2 for Windows 2003 server, in that the COM+ settings (Component Services, root node) have had the "remote activation" security setting permission missing after the update. Don't know if this is your problem, though.
