Trying to use DHCP Server Callout DLL for MAC Address based filtering

[magdeb]

I am asking for help with keeping users off of our regular wired network. I am doing so because we now have a wireless network for guest users. This means they have no need to “plug into the wall” and get an IP address. This practice has contributed to an occasional crisis for the DHCP server when it runs out of IP addresses to dole out.

I have discovered a way to do this which is outlined below but I cannot seem to get it to work.

I found a Microsoft blog which suggests using a dll that loads into the DHCP Service and blocks and MAC address that you list for it. I can pull the MAC addresses from the DHCP of any suspect machine. The problem is I believe I am following the instructions but it is not working as the developer describes and his feedback is sketchy at best. I have attached his instructions for your review.

The premise is outlined at:

I am trying to implement this but I do not see the 1033 event the developer mentions is the sign of successful loading.


Thanks

Although I cannot help with this, you must remember that this does not stop people allocating a static address and accessing your wired network that way. If you wanted complete security, you would have to look at something more network based.

I understand what you are saying. This is to be used as a tool to move users onton the wireless.

Thanks
