The problem come due to higher version ntwdblib.dll available with PHP 5. The simple fix for this problem is to replace the ntwdblib.dll with old version. You can download the Old version of dll file from http://trulymanaged.com/downloads/ntwdblib.dll OR if you have Plesk Control Panel you can directly copy/replace C:\WINDOWS\system32\ntwdblib.dll with C:\Parallels\Plesk\additional\PleskPHP5\ntwdblib.dll

This problem can be fixed by adding stiepreview.dll as ISAPI Filters in IIS. To add ISAPI Filters login to the server and go to IIS > Web Sites > Properties. Then chose ISAPI Filters tab and add filter called “sitepreview” located at C:\SWSoft\Plesk\isapi\sitepreview.dll.

NOTE: “C:\SWSoft\Plesk\” Directory can be changed as per your Server Settings
