DNS doesn't work with neither forwardes nor root servers after each OS
reboot, until DNS service is restarted

based on DNS logs, i can say that it does not recieve responses ffrom
forwarders/ root servers for some reason.

what it can be?

Hi

Can you be more especific about the problem itself and how/when did it
happen, what steps did you take untill now to try to solve, and the DNS
configuration including DNS servers.

Can you give some details as to how the DNS servers is configured?
Forwarder IPs, Recursion settings on both the Forwarder tab and advanced
tab, and whether you are behind a PIX firewall.

Assuming you mean that your DNS server can neither forward nor
recurse for resolving the Internet then the four most common reasons
are:

1) Disabling Recursion (and forwarding) in the ADVANCED tab
of the server options

2) Having a ROOT zone on the DNS server (disables both too)

3) Having one DNS server forward to another which ALSO forwards
back to the first (mutual forwarding) -- never do this.

4) Firewalls that block the DNS server from reaching the forwarder
DNS OR from doing the actual recursion itself.

Only #3 makes sense IF your DNS server resolves through forwarding
or recursion after MERELY restarting it (without making any config
changes.)

IF none of these seem to solve the problem, then I would strongly
suspect a damaged DLL or service and strongly consider a "REPAIR
INSTALL."

so i have

SBS 2003 SP1

DNS host primary zone for LAN domain <company.local>
and has 2 forwardes 4.2.2.2 & 4.2.2.3 for all other domains with diable
recursion NOT selected

root hints are also set correctly



round robin & net mask ordering are enabled
DNS listens for all interfaces

network config is

Connection-specific DNS Suffix . :

IP Address. . . . . . . . . . . . : 192.168.5.100
Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . : 192.168.5.1
DNS Servers . . . . . . . . . . . : 192.168.5.100

PPP adapter RAS Server (Dial In) Interface:

Connection-specific DNS Suffix . :
IP Address. . . . . . . . . . . . : 192.168.5.150
Subnet Mask . . . . . . . . . . . : 255.255.255.255


RRAS also enabled in <LAN routing & VPN mode>

about PIX i do not know

but i already tried dnscmd / config /enableednsprobes 0

it does not solve issues

and also please keep in mind that the problem start from the very OS restart
& lasts to DNS service reboot i.e. < net stop dns & net start dns > with no
other changes

when it started i do not know - since i work with this server not from the
beginning

1) & 2) is not my case
4) also seems not to take place - since even when DNS server can not resolve
www.hp.com. i do can resolve this FDQN via direct request to any of my
forwardes i.e nslookup www.hp.com. 4.2.2.2

Ok.
Adding to Herb response, if you change the Forwarders ip to new ones or if
you remove them using only root hints, does this still happen?

problem persists event if only root hints present and forwardes are clean
option with other forwardes was not tested - i will try it this evening
