Windows Server DHCP 'Enable IP Address Conflict Detection'

So this is just a tiny nugget of information for Windows DHCP administrators. You can help mitigate address conflict detection in your dhcp server by setting the following line.

First you can check if it is enabled or not by running

netsh dhcp server show detectconflictretry

Then, if it is not enabled you can run

netsh dhcp server set detectconflictretry 1

Obviously run with 0 to disable.

netsh dhcp server set detectconflictretry 0

Server 2008 WINS with two NIC's

If you are still running WINS (I do for simplicity) and have two NICs in your WINS box, you will need to change the order of the NICs so WINS knows where to look. This was driving me nuts.

Things I did to resolve the issue.

DNS Server, on the Interfaces tab disable the NIC your non "main" NICs.
NIC, Under "Manage Network Connections" select your non "main' NIC, uncheck all boxes except for IPv4/6. Then select your IPv4 box, uncheck register DNS, and disable NetBIOS.
Still in the Manage Network Connections, select Advanced (File Menu) -> Advanced Settings. Move your "main" connection to the top of the list. Press ok.

You are done, go back and WINS should know be able to resolve/connect.

Disable/Enable Windows IPv6 Tunnels

I just found this link, and wanted to preserve it. Very nice for disabling IPv6 tunnels on Windows machines. I am running dual-stack, and the tunnels felt like they were in the way.
