"Unknown Contact" on permissions for Adobe PDF files RRS feed

  • Question

  • I’ve been doing backups for the last year using xcopy in a bat file under Windows 7 RC without problems.  I put on Win7 Home Premium and now the copy dies after a few minutes with a denied access message.  If I simply drag and drop or edit/copy edit/past the directory it copies without problems. Go figure…


    I found a PDF file I couldn’t open—access denied message, and right clicked it. I clicked share with/specific people and found myself as owner and an account names “unknown contact” which had read/write privileges.  If I clicked on properties/security there was an unidentified account starting with S-1-5-21 etc. I went back and deleted the “unknown contact” and was able to open the pdf file successfully. Take ownership didn’t change the equation.


    Closing and re-opening the PDF file caused the S-1-5 etc guy to disappear.


    After a day of messing around I found only PDF files have the problem and resetting all PDF files to eliminate the “unknown contact” solves the problem and permits the xcopy bat file to run to a successful completion. I used “search” and *.PDF for all directories, then selected all via shift/select and eliminated the “unknown contact” permission.


    Does anyone have any idea what’s going on here? How do these funky accounts/permissions get set?
