This article describes how to properly configure the binding order on a Small Business Server-based computer. Having bindings improperly configured can lead to a number of connectivity and program errors. When you make changes to the network configuration (such as adding protocols, adapters, modems, or services), the binding order can potentially change. Check the binding order whenever you make changes to the network configuration.
A partial list of issues that are resolved by properly configuring the network binding order includes:
133031 Event ID 4280 appears for WINS bound to one NIC
189848 Computers disappear from Manage Computer Wizard in Small Business Server
219364 DHCP disabled when connected to Internet Service Provider

To configure the network binding order:
Quit any programs that are running.
Right-click Network Neighborhood, and then click Properties.
Click the Bindings tab. In the Show Bindings For box, click All Services.
Double-click each listed service to expand it.
Under each service, double-click each protocol to expand it.
Under each protocol, there is a number of network adapter icons. Click the icon for your network adapter, and then click Move Up until the network adapter is at the top of the list. Leave the "Remote Access WAN Wrapper" entries in any order under the network adapter(s).
Note If you have more than one network adapter, place the internal adapter (with Internet Protocol [IP] address 10.0.0.2 by default on a Small Business Server network) at the top of the binding order, with the external adapter(s) directly below the internal adapter.
The final order should appear similar to:
 Network adapter one  Network adapter two (if present)  Remote Access WAN Wrapper . . . [n] Remote Access WAN Wrapper
Repeat step 6 for each service in the dialog box.
After you have verified the settings for each service, click All Protocols in the Show Bindings For box. The entry for "Remote Access WAN Wrapper" does not have a network adapter listed. Skip this item. Repeat steps 4 through 6 for each remaining protocol.
After you have verified that the bindings are set correctly for all services and protocols, click OK. This initializes the rebinding of the services. When this is complete, you are prompted to restart the computer. Click Yes.
