The server process could not be started because the configured identity is incorrect. Check the username and password

We get this error with a C# web application and deployed in multiple servers for load balancing. Retrieving the COM class factory for component with CLSID {000209FF-0000-0000-C000-000000000046} failed due to the following error: 8000401a The server process could not be started because the configured identity is incorrect. Check the username and password. (Exception from HRESULT: 0x8000401A).

IIS we use service account to configure this application.

Can any one help on this. Thanks in advance!

Maybe it is the problem caused by insufficient account permissions. You can try to create a new user on the machine with admin privilege and assign this user on the Identity Tab of the COM service.

In this thread, many users gave different methods.
