Re: Random (seemingly) network disconnects - authentication issue?

Tech-Archive recommends: Fix windows errors by optimizing your registry

Do you have ONLY the Internal DNS server IP in the client's TCP/IP
properties?

Your server should also have ONLY the Internal DNS server IP in the TCP/IP
properties. If it is a DC itself, it should point to itself for DNS. (and
other Internal DNS servers for redundancy, if you like)

Specifically, an ISP DNS server should not appear in the Internal LAN
machine's TCP/IP properties.

Is all that true?

1 2003 Small business server with AD. 6 XP machines connected, 2
wirelessly,
4 wired. Seemingly randomly machines at some point (usually late
afternoon)
will lose connectivity to the server. Not all machines happen at the same
time but it has occured at one point or another to every machine. Happens
pretty much daily. I can still ping the server IP adress from the
affected
machine. IP address seems fine on affected machine (and server). DHCP
lease
is or a week and shows as being from that morning and valid for a week -
so
it has not lost it's IP. Logoff/logon alwaysrestores connection - solves
the
problem. Occasionally while using the machine while not accessing the
network will get a pop-up message saying "connected restored" indicating
that
it lost the connection but restored it. So I think it is a windows
authentication issue. But I am not sure how to proceed to troubleshooting
from here.

Someone said it could be a time server issue and to ensure all machines
point to a time server - i will do that on Monday. 2 main errors in
server
error log are POP3 connection errors 1019, 1023, 1035. And W3SVC-WP
errors
2268, 2214. Nothing else of note I can see.
Any ideas on how best to narrow this problem down now? Agree with my
assessment that it is a windows authentication issue given that I still
have
physical connectivity, valid IP addresses, and logoff/logon fixes?

Help of course appreciated!
