Our Web site hosting company changed the IP of where our company site is stored. Now the workstations on our local LAN will not connect to our web site. We can access any other site we want to from our lan and We can access the company site from anywhere else, just not on any device connected to our LAN.
We have a Windows 2008 server with AD and DNS.
DNS does have forward lookup zone with (A) records for autodiscovery, mail and www
We have a second windows 2008 server with Exchange
Before the hosting company moved the site to a new IP we could access the site from anywhere.
What I have done so far is:
Change the DNS www (A) record to reflec the new IP.
Flushed the cache on the workstations (ipconfig /flushdns)
From a lan workstation ping the site URL and it does return the new IP.
Clear the dns cache from DNS manager.
Add a forwarder pointing to open dns.
There is no Proxy server
When i set the router (which aslo does the DHCP) to only use open dns we can connect to the site from the LAN, but we cannot get email from our onsite exchange server.
Does anyone have any suggestions?
