My clients are connected to a Dell Server 2003, fully patched. There are several external hard drives containing everyday-use files. I ran security patches on the server last night and had to reboot the server. Now the users are getting a "Read Only" tag on all the docs in one particular folder, containing spreadsheets, word docs and ppt's. The Read only tick box is not ticked on any of these files. I deleted all the user rights to these folders, (it's about 40GB), and recreated the rights. This didn't help. I copied all the files to a different Hard drive, this didn't work either.
Are the security patches at fault?
