Re: Internet access problem caused by DNS failure

Thanks for your reply. I think I have that already and I have made no
changes. IPconfig server results below. Router automatically picks up its DNS
servers and DHCP is switched off.

Do I need to uninstall and reinstall the dns server in SBS?

Your SBS should be the only DNS in your LAN and all workstations should
point to that. On your SBS DNS you enter your ISP DNS servers under the
forwarder tab.

Also, if your router is doing the DHCP, turn it off and let your SBS handle
that.

See if that resolves your issues

SBS2003R2 with a number of WinXPSP2 clients. Draytek router with firewall.
One NIC set up. Router is connected to ADSL & ISP's WAN quite happily and
uses ISP's DNS servers. SBS server set up correctly and no recent changes.
I
keep losing web access even though router remains connected. If I run
Configure Email and Internet Connections wizard, I get access back for a
period of time, then I lose it again. Rerun Configure Email and Internet
Connections wizard and back in business. This works if I chose the same
dns
servers sometimes, but always works if I swap them from the choice I have
(BT
Broadband). Any ideas most welcome.
