All other servers are not having this issue - just one Windows 2000
Server. The rest of the environment and DNS looks healthy. The ip
settings on that server have the correct gateway and subnet
assignments. The host file and lmhost.sam files are factory. This
machine just will not ping by name to anything on another subnet. All
machines on the same switch/segment are ok.
We presume it WILL ping by address.
Will it fetch DNS using NSLookup from EVERY one of
the DNS servers listed in the NIC->IP properties or
shown when you do "IPConfig /all".
The symptoms of pinging on the local subnet and NOT
across routers TEND to suggest that you are resolving
local names through NetBIOS broadcasts (which is
a normal fail over mechanism for MS-NetBIOS machines.)
A common reason for client DNS failure (which this seems
to be) is configuring the WRONG DNS server or a MIXTURE
(of internal and external) DNS servers on the client NIC->
IP properties.
By testing explicitly using NSLookup you will prove that the
client can actually contact the DNS listed.
It is also MUCH BETTER to cut and paste the IPconfig /all
output to avoid any typos AND avoid overlooking any
mistakes in the settings (our eyes tend to see what we expect
to see, cut and paste is not fooled.)
nslookup NameAcrossRouter IP.DNS.Server.Preferred
nslookup NameAcrossRouter IP.DNS.Server.Alternate
nslookup NameAcrossRouter IP.DNS.Server.etc
You may only have a PREFERRED but try every one if you
have more than one listed on the client NIC settings (and
for ANY NIC showing in IPConfig /all).
