A few weeks ago I tried to install a new AV on my File Server (this is a Windows Server 2003 Standard server, SP2, attached to my EMC Clariion via an iSCSI connection. Outside of some EMC software and a few small apps, the C: drive is mostly clean). Anyway, the tech noticed it wouldn't install because the Everyone group wasn't at the root of C: as it is by default. In fact, when I looked at the Security Properites of the root of C:, only Admnistrators was listed. I know this isn't right unless it was changed by someone...all my other servers have Administrators, SYSTEM, Everyone, Users, etc. at the root.
Anyway, when I added Everyone and hit OK, it wiped out all my C: permissions for some reason (that is, the Security Properties of any folder or file on C: is blank). Using my other servers as a guide, I manually added the default C: permissions and majde sure they pushed to all subfolders and files (added Admnistrators, Everyone, SYSTEM, Users, and CREATOR OWNER).
This worked fine, and the server has has no issues since then. I tested all the apps, etc.
My question is...I haven't rebooted it yet, but have to soon to finish an install. Should it be OK since it's been fine since the change, or will a reboot potentially cause an issue I might not be seeing?
