I have a COM DLL developed in VC++ where in certain place following statements are executed

hThread = GetCurrentThread()

If (OpenThreadToken(hThread, TANDARD_RIGHTS_REQUIRED |TOKEN_ASSIGN_PRIMARY|TOKEN_DUPLICATE | TOKEN_IMPERSONATE|TOKEN_QUERY_SOURCE|TOKEN_ADJUST_ PRIVILEGES|TOKEN_ADJUST_GROUPS
TOKEN_ADJUST_DEFAULT| TOKEN_ADJUST_SESSIONID | TOKEN_QUERY, TRUE, &horigtoken) == 0
....

In ASP application I am using this COM dll and it is absolutely fine. But after I migrated from the ASP to ASP.Net, I noticed while debugging that call to OpenThreadToken is failing in ASP.Net

In both ASP and ASP.Net application, for IIS Directory Security Authentication Method I am using Anonymous access for a specific local user account created on the server

The error # I get while calling the COM method from ASP.Net is 1008 (An attempt was made to reference a token that does not exist

If anyone has come across such a situation, pls share your thoughts to make it work
