Are all the machines you can ping on the same subnet? If so they are
doing broadcast resolution and other name resolution is not working.
Also test DNS using both FQHN as well as host name so :
ping host
ping host.loc.org.com
And also check WINS resolution there is a RK tool called winscl that can
help in this regard.

Can it be the routing issue? Is either the backup or the server in
question a
multihomed machine? Try putting entries in a HOST file on both machines
and try
pinging again. This way, you will eliminate the name resolution issue
and will
be able to concentrate on a network issue
When you ping by name, which error do you get:
- unknown host..
- destination host is not reachable
- request timed out?

No, we do not have any manual mapping of machines IP address in either
host
file or lmhost file. When I ping any machine by name from this server
they get
resoloved except for few servers. Unfortunately one of them being the
backup
server. So I am not able to do the backup for last 2 days. I just now
tried
ipconfig /flushdns without any luck.

can it be that you have a HOST file with incorrect IP->host mapping on a
machine
from which you cannot ping?
When you ping by name, does it resolve the name correctly? Does it
resolve
the
name at all?

Subject: cannot ping by name
Hi guys,
>From one particular server, I cannot ping "some" servers by name. I can
ping
the same servers by IP address or I can do nslookup. I am sure it is not
name
servers issue because all other machines can ping any machine by name or
IP
address on the network. I also checked the DNS entry on that particular
server, everything looks right. Any thought on this? You can be
sarcastic!! I
don't mind. By the way, this is the only 2000 server on an NT network,
if that
makes any difference!.
