mysterious Ping values

Hi,

I have a network problem on windows 2003 x64 server. The connection
to
another DC in not reliable. When I enter a ping statement, I will get
the following result:


E:\>ping localhost


Pinging mail.weroca.de [127.0.0.1] with 32 bytes of data:


Reply from 127.0.0.1: bytes=32 time=-6ms TTL=128
Reply from 127.0.0.1: bytes=32 time<1ms TTL=128
Reply from 127.0.0.1: bytes=32 time=-6ms TTL=128
Reply from 127.0.0.1: bytes=32 time<1ms TTL=128


Ping statistics for 127.0.0.1:
Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 0ms, Maximum = -6ms, Average = 1073741821ms


I never seen this before. Does anyone have an idea?


thanks
michael

you didn't overclock it did you? if so you may have broken the light
barrier and are sending pings back in time! If not i would bet its a bug in
ping and how it computes the time. most likely some underflow that is being
handled badly when response time is very short in 64 bit math..

I can see any problems. Is mail.weroca.de the FQDN?

mail.weroca.de is the FQDN. The server is only visible inside the lan.
There no difference when I ping to another host or localhost.

I find a thread with the same problem:

How about ping -a localIpaddress and ping -a remoteipaddress?

No difference.The reply with negative values comes much faster than
the correct values.

negative values represent an error.
I would either update or rollback your network card driver and see if it
continues.
