Why we still use WINS when we have AD
WINS... the Windows Internet Name Service. Introduced in, I believe, Windows NT 3.5 in order to allow Windows name resolution to work across different IP subnets. NetBIOS relies on broadcasts for name resolution, and WINS allowed it to work by using a unicast to the WINS server to find addresses. In theory, DNS in Active Directory (now nine years old!) replaced it.
Not for us.
There are two things that drive the continued existence of WINS on our network, and will ensure that I'll be installing the Server 2008 WINS server when I upgrade our Domain Controllers in the next two weeks:
That said, for those machines that AREN'T in the domain the only way they can find anything is to use WINS. We will be using until the University President says unto the masses, "Thou Shalt Domain Thy PC, Or Thou Shalt Be Denied Service." Until then, WINS will continue to be the best way to find Windows resources on campus.
Not for us.

- We still have a lot of non-domained workstations
- Our DNS environment is mind-bogglingly fragmented
