DVD Drive Ownership Blocked

[kahu]

Hi, I have two Acer desktop computers with Vista Business SP1 they both have
blocked security permissions on the DVD Drive. There is a crossed out circle
on the icon, and I cannot access any discs from the drive (it opens empty).
"Access is denied" when I try to access it through the command prompt.

In the Security Properties of the drive the Current Owners is "Unable to
display current owner". I am unable to add a member or group to the
ownership there. Is tells me "Unable to set new owner on DVD RW Drive (E.
Access is denied".
I'm accessing all this through the built-in Administrator account, and have
opened the command prompt as Administrator.

*I have been able to get in through Safe Mode in the Administrator account,
but still have been unble to find a way to open this up for users and admins.

Thank you!

Thanks for the direction.

I have not been able to get the permissions/ownership to open up for me.
I've tried adding all kinds of groups and user accounts to have
full-ownership, but I don't see any change.
[This problem also is blocking USB drives from being accessed]

On all other Vista Business systems I have the only owner shown in the
"Protected Storage System Provider" is SYSTEM.
I'm currently trying the SubInACL reset.

I have finished a reset scan with SubInACL to no avail. I had 6 failures
during the reset, but I'm not sure how to address them.

I am still locked out of changing ownership of all "Devices with Removable
Storage." The owner is still set at "unable to display current owner." And
access is denied when I try to make a change in the Security properties of
the drive.

Check the registry (regedit.exe) and see if either of the following keys
exist:

[HKLM\SOFTWARE\Policies\Microsoft\Windows\RemovableStorageDevices]

[HKCU\Software\Policies\Microsoft\Windows\RemovableStorageDevices]

and if so, are there any entries in the right-hand pane?

Neither of these keys exist in my registry:

[HKLM\SOFTWARE\Policies\Microsoft\Windows\RemovableStorageDevices]

[HKCU\Software\Policies\Microsoft\Windows\RemovableStorageDevices]

I've done a search for "removable" in my registry and
