Slow response despite ok dns...

Hi,

We have a w2k server on which we changed the ip address a while ago. Now
the users experience excess time to log on/off and when opening file
open/save dialogs.

Apparently the server's dhcp service distributes the correct dns server ip
etc so everything 'looks' ok. But does it exist a resource somewhere with
information on which properties to check (server side and client side) in
cases like this...?

Thanks a lot for some hints

Slow logon might be poor DNS settings etc.

Run DCDiag on every DC.

Run NetDiag on every non-DC.

Make sure ALL machines use STRICTLY the internal DNS that supports
your AD DNS zone resolution.


DNS for AD
1) Dynamic for the zone supporting AD
2) All internal DNS clients NIC\IP properties must specify SOLELY
that internal, dynamic DNS server (set.)
3) DCs and even DNS servers are DNS clients too -- see #2
4) If you have more than one Domain, every DNS server must
be able to resolve ALL domains (either directly or indirectly)

netdiag /fix

....or maybe:

dcdiag /fix

(Win2003 can do this from Support tools):
nltest /dsregdns /server:DC-ServerNameGoesHere
http://support.microsoft.com/kb/q260371/

Ensure that DNS zones/domains are fully replicated to all DNS
servers for that (internal) zone/domain.

Also useful may be running DCDiag on each DC, sending the
output to a text file, and searching for FAIL, ERROR, WARN.

Single Label domain zone names are a problem Google:
