The following is a Snip of a production SBS 2008 server:
To get the Advanced Settings screen:
- Start –> NCPA.CPL [Enter]
- Hit the ALT key if the File menu is not seen.
- Click Advanced.
- Click Advanced Settings.
In this case, Local Area Connection 2 is the NIC that was not plugged in during the OS setup phase. Yet, the OS somehow managed to place that NIC at the top of the binding order.
What does that mean?
Network services run slower as the OS will poll the disabled NIC _first_ before the NIC that the services are actually connected to.
So, for any network that is experiencing any kind of slowness the following should be done in the troubleshooting process before touching any of the NIC driver settings or OS internal configuration:
- Check the Switch!
- Gigabit on _all_ ports please.
- Make sure that switches with a higher port density have the internal backbone to handle all or most ports running at full duplex Gigabit.
- Change the patch cable between the server and the switch.
- Verify the binding order on the NICs.
- If a change is needed note that the server would need to be rebooted!
- In the case above:
- Move Local Area Connection 2 to the bottom of the list.
- Uncheck File and Printer Sharing on Local Area Connection 2.
- Uncheck Client for Microsoft Networks Local Area Connection 2.
- Check the Provider Order tab
After a reboot things took a day or so to straighten out. But once they settled down the reports were running in a fraction of the time it took before the change.
