Small Business Server 2008 SP2 - Failed antimalware install, on reboot all drive mappings are gone. Unable to recreate with error "The handle is Invalid". Help!

Question

After a failed antimalware install, on reboot all drive mappings disappeared. I am unable to recreate or create any drive mappings with error "The handle is Invalid". Our data and programs are mission critical and need resolution. Any help would be amazingly appreciated !

Answer 1

As it turned out, I searched the security properties of the C Drive and discovered that the Owner was now "TrustedInstaller". I changed it back to the Administrator and rebooted. The mappings then came up on their own as usual. Not sure if what we changed did it or if the reboot for the 4th time did it. Thanks for the attempt!
