Appendix A
How to Add a Loopback Adapter
For Out-of-Path Mode, a loopback adapter or device similar in function is required.
This appendix lists a few different ways to add such a device for different OSes.
A.1 Installing the MS Loopback Adapter
1. Click Add Hardware -> Add a new device -> No, I want to select the hardware from
a list, and select Microsoft Loopback Adapter from the list and click OK.
2. At the MS Loopback Adapter Card Setup screen hit OK to the default of 802.3
3. You should be prompted for the path to the NT setup files. Click Continue once the
path is correct.
4. Click Close. Reboot maybe necessary. Go to step below for Configuring the MS
Loopback Adapter
A.2 Configuring the MS Loopback Adapter
If not there already, goto Start > Settings > Control Panel > Network > Protocols tab.
Select TCP/IP and click the Properties button
You should be at the Microsoft TCP/IP Properties dialog box. Be sure the MS Loopback
Adapter is the Adapter selected. Enter your farm IP address for IP address (Subnet should
be match your servers, change it if not) Make sure not enter Default Gateway or DNS for this
loopback adapter.
Click Apply, then OK, then Yes when prompted to restart the computer
For Windows 2003 Server, make sure the metric is the highest number in routing table, stop
here.
Note The highest number meaning 1000 is higher than 100. You need to make sure that
the Loopback Adapter has the highest number in the routing table. Giving a lower
number means a higher priority. You want the Loopback Adapter to have the lowest
route priority, therefore a higher number value.
For Windows 2000/NT Systems, please proceed to the Appendix B for remove the route
entry in the routing table.
If you are noticing that the Loopback Adapter is picking up or creating NetBIOS chatter, you
will need to turn off anything related to Client for Microsoft Networks, File and Printer
Sharing for Microsoft Networks, and WINS. Right click on the Loopback Adapter icon, and
click on Properties. In the Networking tab, unselect “Client for Microsoft Networks” and
“File and Printer Sharing for Microsoft Networks.” Next click on “Internet Protocol
Version 4 (TCP/IP)” then click the Properties button. In the General tab, click the
Advanced… button. Click on the WINS tab and unselect Enable LMHOSTS lookup and
