WCF service giving Time Out error

I have a .Net service which is used to connect to Enterprise Architect API. When directly running the .exe file, it is taking about 30 seconds to connect and get response. When registering the same service as WCF service and running it, it gave following error:

Retrieving the COM class factory for component with CLSID
{67F4E0FA-46A7-4255-B084-69A9433D08C3} failed due to the following
error: 80080005 Server execution failed (Exception from HRESULT:
0x80080005 (CO_E_SERVER_EXEC_FAILURE)). 

Solved the above error by following the steps given in this link.

After that now the registered WCF service is taking about 4-5 minutes to connect and then it is giving an error, "tjava.net.SocketTimeoutException: Read timed out."

The problem is that EA requires a "real" user to work properly.

The guys at LieberLieber apparently found a solution for it: Running-enterprise-architect-on-a-server
