I have the following app pool & website structure for different instances of a MVC web application whose design is being upgraded.
AppPool A running with Credential A
- Web App A V1 running with design version 1 **
- Web App A V2 running with design version 2 **
AppPool B - Also running with Credential A
- Web App B V2 running with design version 2 **
** These have different urls
Every once in a while , users of Web App A V2 get the error message below:
'Retrieving the COM class factory for component with CLSID {B2BCFF59-A757-4B0B-A1BC-EA69981DA69E} failed due to the following error: 800703fa Illegal operation attempted on a registry key that has been marked for deletion.'
Web App B V2 running with design version 2 does not get the error, neither does Web App A V1 running with design version 1
I have seen 2 potential causes for this message described, but they do not seem to match the pattern of what works and what doesn't :
Cause 1 in Visual Studio, using 32 bit dlls when 64 bit is required, or vice versa. If this were the problem, then I'd expect
Web App B V2 to also be failing.
Cause 2 in IIS, Admin person has logged in & then logged out with App Pool id. If this were the problem, then I'd expect all Web Apps ( A V1 , A V2 & B V2 ) to fail.
Does any one else have any ideas about what might be causing this issue?
Seems maybe a thread trying to add or update a registry key while some other thread marked the same key for deletion. Do you have a call stack to get an idea about the API that tries to do that ?
No actual smoking gun from these links, but I have decided to see if splitting the V1 & V2 of the apps into their own Application Pools to insulate them from each other stops the problem from recurring. Thanks for your help.

Hi,
Seems maybe a thread trying to add or update a registry key while some other thread marked the same key for deletion. Do you have a call stack to get an idea about the API that tries to do that ?
At worst I would look at https://social.msdn.microsoft.com/Forums/windowsdesktop/en-us/96cd6e6f-bf14-4980-b890-15c1fa5cb57e/how-to-locate-clsid-in-registry to try to understand which component is involved.
Edit: you also have https://docs.microsoft.com/en-us/sysinternals/downloads/procmon that should allow to track registry access.
