MMC cannot open the file C:\WINDOWS\system32\dfrg.msc
[I've previously tried to post this a couple of time, but it doesn't seem to
have come through - I'm fairly sure the newsreader on my other machine is playing up, but apologies if I'm mistaken & you see this twice] Hi there, I manage a small domain with an SBS 2003 server and a handful of PCs running XP Professional SP2, all reasonably up-to-date using Windows Update. I have a shortcut to Disk Defragmenter on my desktop, which is the same on all machines thanks to roaming profiles. It points to "%SystemRoot%\system32\dfrg.msc" When I'm at the server and click on the shortcut it works perfectly, but when I do so at any of the XP machines it fails, giving the error: MMC cannot open the file C:\WINDOWS\system32\dfrg.msc This may be because the file does not exist, is not an MMC console, or was created by a later version of MMC. This also may be because you do not have sufficient access rights to the file. Pasting "%SystemRoot%\system32\dfrg.msc" into Start Run or a DOS box produces the same thing. The file is there, and if I right-click on it I can see that Administrators (of which I am one) have "Full Control" (read, write, execute) rights to it. If I just type "%SystemRoot%\system32\" into the Run box the "C:\WINDOWS\system32\" folder opens, indicating that "%SystemRoot%\" is being resolved correctly. I can find "dfrg.msc" in that folder & double-click on it. The same error. Starting from Accessories System Tools gives the same thing. I have tried running `regsvr32 dfrgsnap.dll` & `regsvr32 dfrgui.dll` to no avail - they say they've completed successfully, but make no difference. (To be honest, I don't know if they should, but when searching I found it suggested to reregister these DLLs, so gave it a go). I have also tried right-clicking on dfrg.inf, right-clicking & choosing install - that helps none, either. This thread http://tinyurl.com/2cjhp8 suggests Doug Knox's .MSC file association fix and also http://tinyurl.com/yoho6b reregistering msxml3.dll. Neither help. This seems to cover just about every suggestion I can find dealing with this problem, although if you can find or think of other things to try then I would love to hear them. I was kinda at my wits' end over this, until I discovered that the defragmentation pane IS available if I right-click on My Computer and choose "Manage". So I can defrag the computers, but it makes no sense at all to me why it works from "Computer Management" but not by other methods - curiosity and the desire not to suffer any bugs on my computers drives me to try to resolve this nonetheless.

MMC cannot open the file C:\WINDOWS\system32\dfrg.msc
Why not do a new desktop shortcut to dfrg.msc? None of the other
nonsense. I don't know the answer is different with roaming profiles.

MMC cannot open the file C:\WINDOWS\system32\dfrg.msc
Bearing in mind the information given below, what do you suggest as a
target for that new shorcut? I am indeed using roaming profiles - this is mentioned in the original post, albeit incidentally. Stroller.

MMC cannot open the file C:\WINDOWS\system32\dfrg.msc
What I do is right click desktop and choose new shortcut. In the
whitebox I type dfrg.msc and next. I type dfrg.msc at the next page and I am done. If you can type dfrg.msc in the run box and it works there is no need to do anything else when you make a shortcut. Are you saying when you type dfrg.msc in the run box it does not run? If so then you need to focus on that. I make shortcuts often enough where all I type in the shortcut is the name of the msc. If I missed the question it would not be the first time.

MMC cannot open the file C:\WINDOWS\system32\dfrg.msc
Hi, Steve.
Thanks for your help. Steve Foster [SBS MVP] wrote: .... When I'm at the server and click on the shortcut it works perfectly, but when I do so at any of the XP machines it fails, giving the error: MMC cannot open the file C:\WINDOWS\system32\dfrg.msc This may be because the file does not exist, is not an MMC console, or was created by a later version of MMC. This also may be because you do not have sufficient access rights to the file. What happens if you create a new .MSC file for Defragmenter, by running "MMC /a", adding the Disk Defragmenter Snap-In and saving that? That works perfectly. It took some fiddling around with the view options to get my new view of Disk Defragmenter to look just like the standard one, but now it is so. I'm still somewhat confused as to the cause of this glitch, but I think I now have a slightly better idea of what .mmc files are now, and the whole concept of that console, so at least I've learned something. Is it possible that the local dfrg.msc files are being copied from the server? SBS is likely to be running MMC v3, XP only has MMC v2, so if the .MSC file has been updated from the server, you would expect to get "...later version of MMC" errors. I don't see how. I can't think of any opportunity for them to be copied across from the server. The only files that are shared from there are the usual soft of documentsy stuff. Right-clicking on the problem dfrg.msc and choosing properties does not (of course!) show any version information. Many thanks for this suggestion. It kinda bugs me not knowing why this has manifested itself - does it indicate that the rest of my systems are just about to fall apart completely? - but now I can click on my desktop defrag shortcut and it works.

Run mmc.exe. Use File - Add Snap-In. Then click Add to see if the Windows Defragmenter is listed - or some other defrag utility. Maybe you installed Diskeeper [Lite] which usurps the MMC registry entry and then uninstalled it but it didn't correctly reinstate the original value. Do you know if all the users have sufficient permissions on the dfrg.msc file? Are they admin-level users (even if in a domain they might have to be special "admin" users but only for their own host and nowhere else)? You are a full administrator on your own host but are THEY also admin-level users on their own hosts (when logged under your domain)? |

I am no PC boffin and am from the old school , but I managed to get my defrag working by going to control panel administrator Tools computer management and clicked on defrag there and it worked. Sometimes the solutions are so simple that we tend to look for the most complicated solutions first. |
