unknown account
Started looking at some file properties, mainly excel, and noticed under the security tab, Group or users names, there is an unknown account showing up that starts with "s-1-5-21 48xxxxxxx - xxxxxxxxxx-...." I did not fill out all the numbers in case it means something?? Have any idea what this might mean. Hope it is normal. Looks like the "guy" has a red "?" on his back.
