Our Network Admin/Server Guru has left us rather stuck, attempting to take over some duties we are not properly trained in (Help!?!) After reading about file permissions in the SBS 2003 R@ Administrator's Companion, we attempted to lock down some folders at the client's request. We removed Everyone - Full Access from the Security list, and added in the specific groups who needed access. After some issues and subsequent consultation with others in the field, we added Creator Owner and System in along with Administrator and the access groups - all set with Full Access. Now we keep getting instances of some files within the affected folders "dropping" the owner, so each file may need to be accessed, taken ownership of, then security groups added individually. This may only affect some files within folders, or all of them. We're not sure what we missed when setting the intial permissions, but would appreciate any input on this - for future reference, as well as to help clear all current issues. Trial by fire......ouch!
