Ping and DNS problem

[Gorleau]

Hi,
I have a network running Win 2003 servers and WinXP clients.
One of them is have a problem since this morning.

It can't seem to resolve the IP address correctly.

When I ping my server01, I should get something like Reply from
192.168.12.101: bytes=32 time=1ms TTL=128

But it's giving some kind of weird IP address from the net. like
this:
72.55.88.44 (fictional)

My DHCP server is ok, DNS server is OK. All the other computers are
fine.

I can Ping this computer from another one.

The configuration on this computer is DHCP, even the DNS server
settings. I tried to do it manually, no luck.

Thank you.

Check your hosts file (c:\windows\system32\drivers\etc\hosts).

you need to give more info..

post you client settings and dns server settings. It appears you are getting
a dummy ip address because of ip/name resolution issues or possibly network
card issues.

Make sure on;y one DHCP server is active. give your network configuration.

I've seen something like this before - it was caused by a rootkit infection

My last post got mis-posted... Also try getting rid of Malware, it can cause
all sorts of problems like this. It could be a TCP hijack.
