Recently, someone asked the following question on an internal Microsoft distribution list:
Can someone please outline the ways in which Exchange 2003 is dependant upon WINS..?
Here's the answer I wrote back:
Exchange 2003 is dependent upon three different things that are related to WINS:
a) Netbios name resolver - this is a service that uses subnet broadcast to let you find the IP addresses of other hosts on your network, based on the name. This is what lets me, on my desktop machine at home, type in \\server\videos and see the share from my server, without any DNS or AD setup. This works fine but only if all of your admin consoles and servers are on the same subnet!
b) WINS - this allows netbios name resolution between machines on multiple subnets
