Can't access intranet sites, even by IP address

[Nolubez]

Ok, have a Galaxy Tab and a Droid 2 (both stock with latest updates), both of which are on my personal wifi, I can access internet sites just fine and previously I could access intranet sites, however only by IP address.

Now, all of a sudden I can't access anything on the intranet from either the phone or the tab.

Any ideas?
