I have a machine called server1 (windows server 2008). It was initially set to have an automatically assigned IP by the DHCP server (windows server 2008). It assigned it 192.168.0.180. I changed server1 to have a static ip of 192.168.0.60. I then deleted the reservation out of the DHCP server. On my local dev machine (windows 7) when I try to ping it it resolves to the old 192.168.0.180 address. I've tried `ipconfig /flushdns' on all the machines, and I've tried rebooting etc. From server1 when I ping it by its name it resolves properly, just not from anywhere else. Is there some cache somewhere that needs to be cleared?

Thanks for the help.

  • It's like the WINS/NETBIOS resolution is getting cached. I've been trying nbtstat and arp to clear it, but not sure I'm doing it right.

  • @MathiasR.Jessen That doesn't seem to be working. Also if I run ipconfig /displaynds there's no entry for server1.

  • Cached result in the DC possibly? -- EDIT: Can you directly ping the fixed IP, and it's just the "Server1" failing to resolve or is the server inaccessible entirely?

  • I don't have a DC setup.

Is that DHCP server also running as a DNS server? If so, clean up the host entry in DNS (delete and/or clear cache).

Update, 20120219

From an other post you made "Can't find computer by name only by IP address", I make up you do not have any internal naming resolution (like DNS, WINS or host-files).

My advice? Unless you want to return here every other month with resolving issues, get an internal DNS ASAP!

  • It's not. Just a DHCP server. We're not running an internal DNS server.

  • Just to be sure: the IP is not in the hosts-file either?

  • Yeah, no IP on hosts file. Did setup a WINS server (on same DHCP server). Will setup DNS on it also.
