DHCP problem

Hi

We are running a Windows 2003 server with DHCP. I am seeing in the DHCP leases folder a blue exclamation mark next to a few IP addresses. what is this and how do i get rid of it?

Also, I am seeing a status of BAD Address next to a few IP addresses, what is this and how to get rid of?

Thanks

Hello,

in short "Expired lease: this address is available for lease by the DHCP server"

Also see:

Where as BAD_ADDRESS is IP address confliction, so the DHCP-server obviously gets a reply when it tries to ping those addresses.

The blue exclamation mark means that the server has run out of leases - have you got a lot of wireless clients?

Try shortening the lease period - try 1 day rather then the 8 day default

Hi,

The lease period is currently 1 day. What can I do to get rid of the BAD addresses and the addresses with the exclamation mark?

Hello.

My colleagues above are quite right.  To remove the Bad Address items, right click and delete from your list (I think if you restart the service it may drop these too but I may be wrong).  You may find that your printers are nabbing addresses.

Long term, the course of action in short summary is as follows:

1.  Check for other DHCP servers and consolidate your scopes to one if necessary
2.  Check for static addresses and create exclusions for them in the DHCP scope
3.  Shorten the lease period (already done)

Best of luck.
Hi, Thanks.

Is there a free tool to scan my network for static addresses. I would appreciate, I already have a ton of static addresses, not sure even if these devices are still on my network.

Thanks
