0xc0000022 error in CHKDSK.exe

Hi there,

When I was installing Office, my laptop hung half way through the installation and I had to restart. I sucessfully installed Office the second time round, however when I try to use CHKDSK now it will not run and comes up with the error 0xc0000022. Since the Office installation I no longer have any restore points. I have tried the command:

CACLS %systemroot%\System32\*.dll /E /G BUILTIN\Users:R

And it either simply doesn't work or tells me Access Denied.

I've tried SFC/ scannow and nothing has changed.

I've tried hitting F8 on restart and going to Startup Repair but it can't find any problems. On the same screen I have tried to run CHKDSK however it tells me that the disk cannot not be locked and it will schedule a scan on restart, however CHKDSK does not open when I restart the computer. I'm totally stumped! Please please help if you have any ideas.

Thanks in advance,

Thom

P.S Everything else seems to be running pretty much fine

Hi again, does anyone have any suggestions...?

Thanks so much in advance,

Thom
