Hi All, I am a IT admin for 200 users here and ran in to this little issue about blocking facebook. So I block facebook from my network using a poison DNS. that work like a charm but now this is ware things start get wearied. after a little while I am got a lot of tickets from my users saying they cant go this web page and that web page and all of these pages have that "log in to facebook" thing. and ever time any of the browsers see that they go looking for facebook. it is so bad that it will forward the users to a search page that says "can't find facebook". I have done: DNS flush, delete all the cookies, deleted all of Temp, disable ever pluge-in I could find.but nothing and it is happening in IE, fierfox and chrome. WTF facebook!
