I am applying new security permissions to folders on a Windows 2008 R2 file server. Using Remote Desktops, I receive access denied errors - seemingly at random. Some folders accept the changes without issue, but others generate the errors.
Alternatively, I've applied the permissions across the LAN via Windows Explorer. This process stops periodically with "unexpected network error occurred" messages. Clicking OK resumes the process until the next error comes up.
I am an administrator on the server. Ownership of the folders is with the server's Administrators group. The folders are on a partition separate from the boot partition.
I appreciate any help.
