I am logged into my domain with my user account but when I access the SharePoint site I am automatically logged in as "Administrator".
I can "Sign in as Different User". However when I change a file it still says last modified by "Administrator" and if I close the window and access SharePoint again I am back to being logged in as Administrator.
If I log into a different PC as me, SharePoint behaves normally. So it appears to be something on my local computer. I've tried deleting everything from IE's browsing history.
I guess it may have started when I logged out of SharePoint and back in as "Administrator" with the PC logged into my user account.
I would really appreciate any help, this is driving me crazy!
