Hi Rick I confused over trying to change this parameter:

<add key="ComServerProgId" value="ppg.PpgServer"/>

I copied my entire project DIR (very small) and recompiled to ppg30402.EXE, then ran ppg30402.EXE CONFIG. Everything works but cannot change this ID? If I change it in web.config then I just get instance not found. The strang thing is the DCOM utility MMC comexp.msc /32 reports a registered ppg.PpgServer but all points to my new location ppg30402\deploy\ppg30402.exe Tried /regserver plenty of times and seems to do nothing.

Can you suggest a fix?
The issue is I want to run duplicate EXE's just rename them and point to different data (seperate deply sets). Thanks Paul

The COM Server has to be registered on the server (CONFIG may do this) and depending on your Application Pool Impersonation you may have to register the COM server (or machine accounts) with DCOM.

Thanks Rick In the end it was Directory permissions nothing related to IIS. The red heerings was that it would register an old server name and go in and out of working.

In the end stubbornness wins. Cheers Paul
