DHCP server -> conflict IP

[FlexyZ]

Hi

I have a DHCP server enabled on one of my interfaces, but clients have problem getting IPs back - after reboot of windows machines it normally works, but this normally not an issue with other DHCP servers.

Here is one message ->

An error occurred while renewing interface Local Area Connection : The DHCP client has obtained an IP address that is already in use on the network. The local interface will be disabled until the DHCP client can obtain a new address.

PA-500:

10.119.20.104   conflict IP        offered

10.119.20.100   conflict IP        offered

10.119.20.105   conflict IP        offered 

10.119.20.103   3c:07:54:46:4a:41

Any clues?

Thanks

Hello,

We are looking into this issue.  May I ask what settings you have for "lease", "mode", and "Ping IP when allocating new IP"?

Thanks,

Nick

Hi Nick,

I have the same issue.  I have the lease time set to 'unlimited' and ping is ticked.

Thanks,

As I recall I had "unlimited" lease and not sure about "ping" was checked - but would think so

Now I have a 8 hours lease time and "ping" checked - will report back

Thanks

Just added a windows 2008, and when fetching DHCP windows was showing a "IP conflict" dialogbox

I am using 8 hours lease, and "ping" option

Thanks
