I have gone through all the topics in the forum regarding this issue they did not worked. The problem seems that I cannot install x86 version of native client because my server is x64. however I cannot change the server so we need to figure out a way through it

regadrs,

According to technet.microsoft.com/en-us/library/cc296170(v=sql.105).aspx:
The x86 version of SQL Server Native Client is required on the computer where PHP is running. If you are using a 64-bit operating system, the x86 version of SQL Server Native Client will be installed with the x64 version of SQL Server Native Client (do not install the x86 version of SQL Server Native Client on an x64 operating system).

So try reinstall the x64 version of SQL Server Native Client.

I have uninstalledandre installed and re installed and restarted the server couple of times. Also I regenerated the files. Still no change. I am getting the same error

As said in http://www.hkvforums.com/viewtopic.php?f=4&t=32071:
As of PHP 5.3.15 / 5.4.5, this COM extension requires php_com_dotnet.dll to be enabled inside of php.ini in order to use these functions, read: http://www.php.net/manual/en/com.installation.php

Are you sure you have enabled the COM extension in your php.ini properly?

Make sure php_com_dotnet.dll does exist in the PHP extension folder specified in php.ini.

yes it is there

I added

[COM_DOT_NET]
extension=php_com_dotnet.dll

lines to my php.ini file need to do nything else?

After customizing your php.ini file, then make sure you have restarted your web server.

still no change

Make sure you have configured your application pool in IIS and set "Enabled 32-Bit Applications" to True, see Introduction to PHP and MySQL in the help file.

it is enabled now but still no change I am gettingth same error

Make sure you install x86 version of PHP 5.x, not x64 version.
