WINDOWS TIPS AND TRICK

Restoring Netapi32.dll Through System Restore
1. Click the 'Start' button in Windows, expand the 'All Programs' folder, then expand the 'Accessories' folder and, finally, expand the 'System Tools' folder. Click the 'System Restore' icon.
2. Click 'Restore my computer to an earlier time,' then click the 'Next' button.
3. Click a restore point on the calendar. The restore points are represented by bold dates. If you happen to know when netapi32.dll was deleted or corrupted, select a date from just before that time. If you're not sure, select an early date toward the first month of the calendar. After clicking your restore point, click the 'Next' button.
4. Review your chosen restore point on the confirmation screen, then click the 'Next' button. In Windows Vista, this button says 'Finish' instead. As soon as you click it, your computer will begin the restore process and then reboot, which will take several minutes.
5. Click the 'OK' button on the confirmation dialog box that appears after Windows boots back up. This completes the restore process.
Replacing Netapi32.dll Manually
6. Open your Web browser and download a working copy of netapi32.dll from a reputable .dll download site. There are several sites that offer free copies of common .dll files like this, but you can find a direct link to a reliable download location in the Resources section below. Just click the download link and save it to your hard drive.
7. Unzip the .dll file if necessary. Many .dll files downloaded from the Web are compressed as .zip files. If the file you downloaded is a .zip file, double-click it to open it in Winzip or your computer's default unzipping utility. Click the button that says 'Extract,' 'Unzip' or 'Unpack' and select your desktop as the file location.
8. Open the Windows system folder. To do this, double-click the 'My Computer' icon and navigate to the folder location. If you're using Windows XP or Vista on a 32-bit system, the location is 'C:\Windows\System32.' If you're using either of these operating systems on a 64-bit system, the location is 'C:\Windows\SysWOW64.' If you're using Windows 2000 or NT, the location is 'C:\WINNT\System32.' If you're using Windows ME, 95 or 98, it's 'C:\Windows\System.'
9. Drag the netapi32.dll file from your desktop to the system folder. If you're asked if you want to replace the existing file, click 'Yes.'
10. Reboot your computer. Upon booting up, netapi32.dll will be automatically registered or reregistered in the Windows file system.
