I have a project which has 2 parts - an exe and an ActiveX DLL. Earlier I could have the 2 parts running in separate instances of VB 6 simultaneously. Now when I am trying to run the exe portion from VB environment, with the DLL running in a separate VB instance, I am getting the error "Error 70 - Permission Denied". To make any changes to the DLL part, I have to save the project, compile it to a DLL and then run the exe again. Needless to say, this is extremely irritating and time consuming.

The only change that I recently made to my machine setup was to add the IUSR_<MACHINENAME> user (Internet Guest Account) for my ASP applications running on IIS. Does that have any bearing on this ?
