DNS issue in windows XP....

[Guest]

I have a windows XP professional installation on my laptop
I do connect to an AD domain when at work.
While I am traveling, however I login "offline so to speak"

a funny thing happened to me lastnight when using outlook
it was unable to find my email server BY IP,
it kept asking me to relogin... I thought my configuration settings were
somehow hosed up, so I retyped my userid and password (this is authenticated
outbound mail) didnt help, so then I removed my internet mail settings
(outlook 2000) and quit outlook, then restarted outlook and recreated it.
still no go...


I then open a command prompt window and do an nslookup (return) going into
the shell, and it uses my bellsouth DNS server as the default name server..
(as expected) I then type in my mail.company.com to see what it finds...

it replies with a non-authoratative (expected)
mail.companyname.com.mydomain.com (this was NOT expecteD)
and the IP it gives is incorrect, its actually the IP of my POP3 server...?!?!

I expected a standard non-authoratative response
mail.companyname.com
ip address xx.xx.xx.xx


this happens after a reboot as well, and it has me a bit stumped...

I have statically assigned the DNS primary and alternate
and made sure append this computers domain was disabled.

it replies with a non-authoratative (expected)
mail.companyname.com.mydomain.com (this was NOT expecteD)
The LAN is a standard hotel fast access via HAMPTON INN SUITES...
they give a private IP that is 10.6.x.x totally different subnet then my
companies private network and it is being learned via DHCP.

anyone have any ideas?

DNS clients (on your computer) have the option of appending a suffix to
every lookup request. This is standard and the oddball constructions
(such as companyname.com.mydomain.com) usually fail.

Yours isn't failing for some reason. Try disabling domain suffixes in
your DNS client (Windows on your laptop). Of course, this will require
you to always type in a fully-qualified domain name (no abbreviations).
