I couldnt find the DCOM configuration tool I used to use I got from OSIsoft, not an official though. Remember? Can anyone help me downloading that file please?
The utility you are asking for is not an official OSIsoft product and hence not available for download. The tool is supposed to be used in the scope of Technical Support cases only and to be removed after usage by the Technical Support representative.
What's available for download is the DCOM Security and Configuration Guide for OPC which guides through DCOM configuration based on OSIsoft's recommendations.
Also, from my experience, I would definitely recommend just going through manually. This way you have full control over the changes and if your OPC Server and OPC Client (interface) are running under different account or machine accounts, it's much easier to configure security directly in component services.
