i downloaded msvcr71.dll and tried after putting it in system32 directory.. or system directory but no improvement

In your comment you said it was placed in the c:\php\ext directory and in the path, but there is no mention that have enabled the extensions inside the php.ini:

extension = php_oci8.dll
extension = php_oracle.dll

Please attach a copy of your php.ini so we can review it.

Well, I am out of options. Maybe one of the other EE experts have some ideas on where to look next.

Now if you had a Linux server, I could get you up and running in no time with Apache2/PHP5/Oracle client.

This is one of the reasons I don't recommend running Apache/PHP on Windows boxes, especially for Oracle interfaces as they are very picky and require a bit more to get working.
