(SBS) Mail and WWW for laptop users

[news.iinet.net.au]

I am running Win2KSBS with ISA and Exchange.

My domain name is company.local. Publicly my internet domain is company.com.

The router which is connected via a second NIC to the SBS server has a fixed
IP address provided by the ISP of 203.xxx.xxx.246. Internally the IP
addresses are assigned by DHCP in the range 192.168.0.10-192.168.0.100

The MX record is pointing to 203.xxx.xxx.246, the website is hosted at the
ISP.

My question relates to laptop users (mixture of Win98 through to XP) who
need to access emails and the company web page from both inside and outside
of the LAN.

Outlook is setup to obtain email from 203.xxx.xxx.246 which works fine from
outside the lan. They can also access the webpage www.company.com from both
inside and outside the LAN. But they can't get their mail from inside.

So I added a zone to DNS called company.com and a "A" Record called mail
(pointing to the server address internally) so that email works both inside
and outside. I modified Outlook to get mail from mail.company.com and mail
now works fine both from inside and outside. But now the users can't access
www.company.com from inside, although they can browse everywhere else.

I have added both the SBS server and the ISP's DNS IPs to the DHCP scope,
thinking that if the SBS DNS did not resolve the www it would go to the ISP
and resolve correctly there but this did not make any difference, unless I
have a setting wrong of course.

I have seen a solution to add a hosts file (with an entry reflecting the
internal IP of the server) to the laptop but I doubt that would wotk since
the host file get read before dns and therefore would work inside but not
outside.

Any ideas?

Regards

Eric

Hello Eric,

Thank you for posting here.

Based on my research, this problem should be related with DNS. You could
check the DNS settings:

1. Forwarder in DNS console.

2. Delegate www.company.com to the external dns server

3. Use only the SBS server as the DNS server for the internal users.

If you have any questions or concerns, please do not hesitate to let me
know. I am happy to be of assistance.
Thanks and regards,
Alex Zhang

Hi Alex

Thanks very much for your reply and my apologies for not responding earlier.

Your points 1 and 3 were already done, but point 2 was not. I delegated
www.company.com to the ISP's DNS server and everything worked fine.

Before this I had never used/understood delegation so I have learnt
something again! Such a simple solution compared to some of the solutions I
was seeing around the web.

The only issue I had was when the user typed comany.com into IE without the
www it didn't work. But an hour or so later it all started working so I'm
assuming it just needed time to propogate.

Anyway, thanks again for your help.

Regards

Eric
