Microsoft Security Advisory (950627) - Help
So, as requested in this advisory, I entered the command line on one of the
computers here to disable the jet database engine: Caution, read the rest of this post before entering this line... echo y| cacls "%SystemRoot%\system32\msjet40.dll" /E /P everyone:N So, that sets it as it should. Come to find out, some of the programs on the computer require the access to that specific .dll. Fine. I'll re-enable it using the instructions also listed an undo procedure... the advisory states to enter: echo y| cacls "%SystemRoot%\system32\msjet40.dll" /E /R everyone I get "Access Denied". Anyone have a suggestion on how to re-enable the msjet40.dll? |

Did you tried the |keys in the registry to adjust to loosen its grip a little bit?.

Thanks for the links. The 1st one is the exact tech note that tells one to
disable the Jet Engine and how to re-enable on the WorkArounds. The others do not mention what happens or how to fix when the re-enabling fails. I am 99.9% sure this drive was not compromised. Why? It's never been hooked up to the internet. Yet, mandates from upon high (management) say 'you have to disable this'. (Ridiculous if you ask me, that one has to do things for computers to prevent it from attack when it'll never be effected through the internet or e-mail). Yet, also, no one around here where I'm located knows how to re-enable it.

The fix:
Copied the .dll from another machine (same version) onto a CD. Started the 'broken' machine in SafeMode/CommandPrompt. Deleted the 'broken' .dll then copied the new one to the same location. Rebooted. Viola. Works fine. Gah. "KC" wrote: Thanks for the links. The 1st one is the exact tech note that tells one to disable the Jet Engine and how to re-enable on the WorkArounds.
