Title: Multiple DHCP reservations showing for a WHS 2011 server that has a static IP?
Post by: Austinbike on February 28, 2015, 02:39:57 PM

I am running Windows Home Server 2011, this is based on windows Server 2008 (64-bit).

I have a static IP set up for the server, it has had a static IP for the last 3 years.

I was checking my DHCP table on the DIR-655 and for some reason the server was taking 10 DHCP IP reservations (always the highest 10 in the range I believe.)
Rebooted the router to clear all reservations, then rebooted the server.  After the reboot the usual suspect devices all started grabbing IPs. Then a few minutes later, 10 IP reservations show up for the server again.

I tried pinging the IPs and accessing them with a browser. Pings time out, no browser access.

The weird part is that all 10 have the same MAC address, the address of the server.

Swapped out the NIC to a new NIC.  Same thing.  Now 10 reservations with the new MAC of the new NIC.

Has anyone seen this before?  It is puzzling and I am concerned that it could be some issue, it is definitely not right.

• What Hardware version is your router? Look at sticker under the router case.
• Link>What Firmware (http://forums.dlink.com/index.php?topic=47512.0) version is currently loaded? Found on the routers web page under status.
• What region are you located?

How are you using the 655 router? As a main host router or 2ndary router?
Possible that having two DHCP servers online are causing this effect. I have not seen this issue on my 655s, however I haven't ran an additional SW Server...
