I have something strange happening here.  Users are losing their connection to a server running a license manager for Autocad.  When this happens and I ping the license server by name from their workstation I get an ip of 216.139.250.120.  It should be 10.1.1.2 since it is set as static on that server.  If I flush the DNS cache and do an ipconfig release/renew on the workstations, the license server’s correct ip address shows, and they can open Autocad.

I just tried pinging the backup domain controller from my workstation and I get the same address, 216.139.250.120.  Any idea what is causing this?  When I look up 216.139.250.120, it shows a company called networking@hostwaydcs.com.

We use AD integrated DNS. I checked all internal DNS settings and that 216. address does not show up in forward or reverse lookup zones.

Any idea what is going on here?
  Thanks,
cja
