I have solved the problem temporarily by compromising as below.
I have followed the same guide. But only the cahage is instead of creating the registry entry. I have created a text file with name isapi_redirect.properties and placed in bin folder. Used 32bit isapi_redirect-1.2.28.dll.
The environment is as below:
Windows 2003 Enterprise Edition(64bit)
IIS 7 (64bit) but isapi_redirect.dll is 32bit
But still I want to use my application completely with 64bit environment, if I use 64bit dll it is not working. Can some one help me if there are any additional steps to be done.
Thanks & Regards,
