When I go to shutdown my computer it says Mmtask has caused an error in IPHLPAPI.DLL Mmtask will close now. What do I need to do to fix it? Flight Instructor

Try Going to control panel >> folder options >> click the "view tab" Put a dot next to "show hidden files and folders" Uncheck, hide file extesions for known file types. Uncheck, "hide protected operating system files" Then go to Start >> Run >> type, msconfig and click the "Extract File" button. In "specify the system file you would like to restore" put, IPHLPAPI.DLL >> click Start. In "Restore from" put, C:\WINDOWS\OPTIONS\INSTALL Or failing that: C:\WINDOWS\OPTIONS\CABS In "Save file in" put, C:\Windows\System Click Ok, Now when it asks you to overwrite and save the original file, say yes. It will put the original IPHLPAPI.DLL file in MSconfig Backups. Does that work ? If not, try doing the same only instead of putting IPHLPAPI.DLL put, MMTASK.TSK That's MMTASK.TSK Now. All you've done is replaced the two files that were generating an error message and replaced them with new versions. You have the Backups for them both so they are easy enough to swap back if need be.

I fix this problem with the hotfix download from the url http://support.microsoft.com/default.aspx?scid=kb;en-us;279866. Maybe this problem is common. I tried the solution in the response 1 and not fix the problem. Cordialmente, Camilo Gómez

I have tried this prodedure and when I click OK to save file I get an error saying that the file is protedted and can not be moved or deleted.
