[mrdance]

I am running a server with a dynimic IP. I get my IP automaticly. I have three computers on a switch. I am using

http://www.dynu.com

dns service. I got this error message and the server was temporary down from the internet. Any ideas?

Thanks / Henrik

I think your ISP has a problem with his DHCP servers... maybe 2 of the DHCP servers have overlapping IP ranges and both servers leased the same IP address to two different network cards... Peter Van Eeckhoutte

A couple of quesitons:
What kind of Internet access are you using? Are you on a dial up or cable/dsl? Are you running NAT or are you behind a firewall? If not NAT, are you running proxy? Do you have more than one NIC? I tend to agree with Peterve. It sounds like your ISP has handed out you IP address to another client somewhere on there network. Thats why I was asking if you were on a dialup. If you were running NAT then you wouldn't see this error on your server as the conflict would be contained locally to the router if you so running. If this happens again try this:

From the command line type:
ipconfig /release_all
ip config /renew_all

This will lease you a new IP from you ISP's DHCP servers. This should at least get you back on the net for a while.

All Complaints Will Be Routed To /dev/null

I have 10mbit connection which I get from a switch in the cellar of the building. I don't enter any proxy settings. I am running a software firewall. Only one network card.

So if the ip changes when doing ipconfig /renew the ISP has a conflict, or?
