Here is the configuration and then I will explain the problem:
1 Windows 2003 server DNS and DHCP running on sigle server.
10 Windows XP users
Currently when the domain is setup using the name of the company which is also the domain name for their registered website i.e www.xyz.com is doamin xyz.com on their network. They host thier own mail exchange server, dns and dhcp on the same machine. DHCP is setup to provide the local domain server as the primary and the secondary is the DNS server IP provided by the ISP. Everything runs fine no problems...except when they try to access their website hosted offsite DNS does not resolve to the website offsite nor can the website be pinged internally. The only work around I have found is to switch the primary and secondary DNS servers and then they can access it however this create a major slowdown when logging on to the netwrok or accessing server resources as well as the users cannot connect to the internal exchange server, it continues to say trying to connect. The internal DNS is set to forward requests to the ISP provided DNS server but still they cannot get to the website. In other offices I consult for when I name the domain something other than the same name used for the web address there are no problems so I assume their is just some record I am missing in DNS to allow this url request to be forwarded out and resolved to the ISP doman.
Does anyoe have some suggestions I can try to figure out what is going on?
Thanks for your assistance.
