Microsoft Server;Windows Networking;Dynamic Host Configuration Protocol (DHCP)
Hello,
We're having some strange problems with DHCP and some strange IP address assignments. The IP adress has itself as the hostname and has a very long unique ID. They're also showing as BOOTP/DHCP.
I've attached a picture so you can see what I'm talking about. There's an example of one there, but they happen all through out the day and without deleting the entries we'd rapidly run out of IP addresses.
You can't ping the IP's and Wireshark doesn't pick them up either.
I've trawled the web and have seen that others have had this problem but i can't find a definitive answer as to what it is or how to properly track it down.
To me it's like something is very briefly contacting the DHCP server and then dropping straight away, and then it keeps trying. But it's doing it so quickly that not even Wireshark can see it!!
Any help would be greatly appreciated.
Many thanks
