On the same box, we have 4 COM Servers running. When I have only that, the DLLHost.exe file, usually two instances in Task Manager, are not affected. But, when this is on a box running also a bunch of VFP EXE running in WWC file mode, this will trigger some process on the DLLHost.exe files. In such a situation, we'll do as you say by doublechecking the IIS settings for that isolation. The default is not low. So, that might be the situation.
