So this is really stumping me. Starting this Monday I cannot Modify folders on my external. I can create them and open them but cannot save/rename or other modifies. I first noticed it because our remote IT company installed updates on Sunday and all the Microsoft update temp files were still on the drive and not deleted afterwards. When I started to play around with it I realized I could no longer modify anything on the external and would get an error saying "You require permission from administrators to make changes to this folder". This was odd to me because I thought I was the administrator. However I checked my user group and somehow I was placed in HelpLibraryUpdaters group- looked this up and has something to do with BITs and windows updates but was discontinued with Win7, which I am running. Anyways, switched my group back to Administrators. After that I got into Security and made sure my user had full access and ownership of drive and all subfolders and files. This worked to where I have the correct permissions and ownership for everything but still when I try to modify it said the original message but instead of administrators it now says I need permission from myself. It requires permission from Madison(our company domain) rbrown-which is me!!!!! To test if it was a profile issue I gave permissions and ownership to localadmin and logged on as that user and it give me the same error except now it was computerlocaladmin- the user I was logged in as. I have also checked local and domain group policies to see if anything was set to block modify access to externals and there is nothing. I also get error that Recycle Bin is corrupt on drive but cannot delete it cause I need permission from myself I think I have provided all the information I have even if some might not be relevant but feel free to ask for anything else, I am at a loss on what to do now. Please help.
