My admin share C$ has been removed causing our server managed security - Sophos Endpoint Security and Control, to stop updating this client because it is unable to create local tasks. I've searched for two days now, lots of stuff about disabling C$ or allowing network access via a regedit - but nothing about restoring a missing "default admin share C$". OK I can recreate C$ from the mmc but it's removed on a reboot. System is Win7 Pro 64-bit on a domain Very grateful for any help... Nick
