Hi,

i have a problem when i did a ping in my new AD 2003. i have 2 DC also a dns
server. the 2 DC server dns IP settings is pointing to itself. 1 file server
dns setting is pointing to the 2 Dns server internally.
My AD name is 'ael.ms.sg', DNS are AD-integrated.
Problem here: when i do a pinging of any invalid hostname, it returns:

C:\Documents and Settings\Administrator>ping test
Pinging test.ms.sg [203.117.178.39] with 32 bytes of data:
Request timed out.
Request timed out

this [203.117.178.39], is not our IP. i did a ping of ms.sg in my office and
also return with [203.117.178.39]. I guess this is a external IP with a valid
domain call 'ms.sg'.

Anyway, when i did any invalid host, it should return 'time-out', instead of
forward to external to resolve.

i did another test:
In my DNS server, i create a forward zone 'microsoft.com', with empty host
record. i did a ping 'www.microsoft.com', it return:
Pinging www.microsoft.com.ms.sg [203.117.178.39] with 32 bytes of data:
Request timed out.

Without the forward zone 'microsoft.com' in my dns. i ping
'www.microsoft.com', it returns with:
>ping www.microsoft.com Pinging lb1.www.ms.akadns.net [207.46.19.60] with 32 bytes of data: Request timed out.

this is obviously wrong!

The below is the IPconfig/all on my DC1

Microsoft Windows [Version 5.2.3790]

workaround:
i remove the 'Append parent suffixes of the primary DNS' tick, in DC1. i did
the same ping. Now, it replys normal as in 'ping request could not find host
test.' Which this is a normal reply for invaild hostname.

This is not a good solutions and it should not forward to external to
resolve anway, plus the return of ping 'www.microsoft.com.ms.sg' is stupid..

any clus what's going on with my DNS?
