How to Fix iisutil.dll Error

By Pete F Morgan

"Iisutil" is one of the many DLLs installed together with the Windows operating system. Regardless of the version type, Windows OS always have these files as essential components needed in running various programs. Being a DLL file, iisutil has the tendency to be corrupted due to several causes. No matter how nerve-racking these error messages may seem, there are several courses of action you can perform to repair these issues in no time.

Restart Computer in Safe Mode

"DLL" errors often emerge because several conflicting files load in the computer. Know whether these conflicting files are loaded during startup by logging into Safe Mode, which minimizes the number of drivers loading on startup, which makes troubleshooting slightly easier.

Restart your computer and log on to Safe Mode by choosing it among the Advance Startup Options upon rebooting the system. If the error didn't show, it means that one or more of the processes and drivers loaded on startup caused the problem.

Trace the Error's Possible Cause

Different procedures will help trace possible causes of the error. Among the first ones is taking note of the programs you installed or uninstalled. Think if the error appeared after placing new software or after uninstalling a program. Changes in system configuration brought by installation and un-installation process can trigger these errors. If these errors appeared after these procedures, undoing those might solve the problem.

Disabling several startup processes and drivers using "msconfig" will also help pinpoint the issue. This, however, requires trial and error by disabling and activating one file at a time to see the probable triggers. It may take some time, but it will be beneficial in solving DLL issues.

Replace "iisutil" File

A corrupted and/or outdated DLL file is the common reason why these problems show up on your computer. Replacing this file is easy by downloading a newer file version from its developer. Avoid getting this DLL file from other websites because there's no guarantee that you'll obtain authentic and clean files from these sources.

Register the file Manually

Replacing the original with a new "iisutil" often repairs the problem. There are instances, however, when this procedure didn't do anything to fix the inconsistency. To solve this problem, register the new dll file manually through its developer's register server.

For this procedure, access command prompt by typing "cmd" on the Start Menu's search box. Right click and select "Run as Administrator". Type "regsvr32 /u "iisutil"" then press Enter, which will unregister this file. After the first procedure, try to type "regsvr32 /I "iisutil"" to re-register this component.

Scan for Virus and Other Threats

Malware attacks are now prominent due to the popularity of the internet. Hence, the probability of experiencing malware-induced inconsistencies is high. Scan your computer using a well-known and high-rated virus protection program to clean the system from these viruses. Before scanning, be sure to update the virus protection program to guarantee that its database lists the latest discovered malwares and protect your computer from them.

Use a Registry Cleaner

Registry footprints record paths going to DLLs when programs are installed. There are times, however, when paths and handles including DLLs become corrupted or broken, which results to iisutil errors. With registry cleaners, broken paths and mishandled registry entries will be cleaned. Once cleaned, it will let the registry rebuild these paths to fix the issue.

One of the vital things to remember in using registry cleaners is to go with paid and reliable versions to assure effective cleaning procedures. Find top rated registry cleaners online then download for your computer.
