Resolved XP Defrag Error: Cannot load resource DLL. Contact system administrator

XP Defrag Error: Cannot load resource DLL. Contact system administrator.

XP Home, SP3 with all current updates installed.

I have tried,
Hard driver error check.
The system is clean of viruses.
sfc /scannow did not correct the problem.

Any idears?

Have you tried Renaming the existing explorer.exe to explorerOLD.exe and copy another copy across into C:\windows?? Best not to reboot either when performing this

edit

thinking this may be the cause as it is quite common.

Now that's what i call out of box thinking. I'll do it.

Copied explorer.exe from a good computer to the problem one. Still the same outcome.

In DOS i get

In Windows i get

I see no option in the add or remove to add the defrag program.

Ummm ok... try and run sfc /Scanboot from the CD & also /Purgecache I know you ran sfc /scannow but try this way and see what happens.

Have you considered a virus scan also? and a system restore?

edit

Had you any disk errors...? run chkdsk..

sfc is present on my XP SP3 CD but is compressed SFC.EX_ Unable to run. I'll try in windows...

Machine has had a full virus scan with various types of software -> None found!
A system restore will not help if i don't know the date when the problem started. Might of been 2 years ago for all i know.

You have tried a repair install?

Or you could;

It is possible just run the installation again over the top of the original... see if that fixes the issue, I have done this before just clutching at straws but it solved my issue at the time, not ideal but it is effective.

I can't risk doing this as it may affect the currect programs on the machine. There has to be another way surely.

The sfc / scanboot is working in windows. I will try the sfc /Purgecache when it finishes.

Ok try this Click Start then hit Run then type %Windir%\Inf and then click OK > Right Click the dfrg.inf file and then click Install. see if that works.

If it still fails to start type these commands in Start Run box one by one;

regsvr32 dfrgsnap.dll
regsvr32 dfrgui.dll

There was 2 files missing from the inf directory dfrg.inf and dfrg.pnf. I copied over from a working machine and pick install with no result.

regsvr32 dfrgsnap.dll
regsvr32 dfrgui.dll

Failed with an error.

LoadLibary ("dfrgsnap.dll") failed - The specified module could not be found.
LoadLibary ("dfrgui.dll") failed - The specified module could not be found.

Look like a lot of the defrag files are missing here.

Here's the dfrg.inf file.

Ok I found this here;

I'm running out of ideas LOL

Got it working.

I was missing these and copied the files over from a working machine.

c:\windows\inf\dfrg.inf
c:\windows\inf\dfrg.pnf

c:\windows\system32\dfrg.msc
c:\windows\system32\dfrgfat.exe
c:\windows\system32\dfrgntfs.exe
c:\windows\system32\dfrgres.dll
c:\windows\system32\dfrgsnap.dll
c:\windows\system32\dfrgui.dll

Then did......

I have included all the files and a readme for anyone else with the same problem. XP SP3.

Thank you Makcalable for the great indears it really helped.

Tenacious LOL

Well done buddy!
