Technically, this isn't a new feature, as it's been available in all networked versions of Windows. If you're running a small network, you can speed up access to shared folders and files on other computers by creating an LMHOSTS file. This file is like a telephone book that the computer uses to lookup IP addresses for the different computer names on your network. This file can save a second or two each time your computer searches for a computer on the network. Just perform these steps to make an LMHOSTS file:

1. Click Start and then click the Run command. In the Open text box type c:\windows\system32 and press [ENTER].
2. This opens a window to the system32 directory. Click the File menu, point to New and click on Text Document.
3. Double click on the New Text Document icon. On each line of the LMHOSTS file, type the name of the computer and the IP address of that computer. For example:
   192.168.1.1 GATEWAY
   192.168.1.2 MYSERVER
   192.168.1.3 MAILSERVER
4. After typing in the IP addresses and names of the computers on your network, click the File menu and click Save As. In the File name text box type the following exactly: "lmhosts"
5. It's important that you include the quotation marks so that the file isn't saved as lmhosts.txt. The LMHOSTS file does not have a file extension. Now when you try to connect to a computer on the network, your computer won't have to broadcast over the network in an attempt to find the IP address of the destination computer. It'll just look in the LMHOSTS file and make the connection right away!
