 |
|
I encountered a situation where the host name returned by the dns server
differed from the computer's actual name (as obtained by running nbtstat -a
ip_address). How could this have happened, and how can i retrieve a
computer's actual name (as returned by nbtstat)?
Thanks in advance.

The NetBIOS host name can be quite different from the DNS host name.
There's not a "right" or "wrong" host name.
What name to use depends on what services you'd like to use.
When you do file stuff ("copy myfile \servernamesharenamethisdir") then
you should use the NetBIOS name.
When you do Internet stuff ("http://thisname.thatdomain.com") then you
should use the DNS name.
Apart from that - the reverse entry (PTR; IP -> Name) in the DNS could
simply be outdated. Will the forward entry (Name -> IP) work in DNS?

netbios and tcp/ip are two different network ptotocols and have two
different address spaces with different name service providers (e.g. dns
for tcpip and wins, lmhosts, nbt for netbios).
micro$oft is using netbios as primary network protocol and tcpip as
underlayer protocol (could be ipx, apple talk, decnet etc).
the dns name is not equal to netbios name by design and
microsoft box running netbios over tcpip will ask dns for name
on 6th place after all other lookups.
microsoft from windows 2000 moving towards to tcpip as a primary
network protocol and implement the idea to match the host name
(first name from full dns name) as netbios name.
check msdn site for details or search google, e.g.
