I have 2 DHCP/DNS Servers which connect to a sonicwall pro 2040. I have been having problems getting onto the internet or receiving and sending email through MS Outlook (OWA). I have reset the DNS/DHCP Servers and Domain controllers, but still cant get through Sonicwall. The only way my users can get through sonicwall for email is if I log onto th sonicwall through one of the servers. I have had sonicwall run through the settings and all them are correct yet both servers point to its IP as the gateway IP. The other problem is that when I log onto the sonicwall all other users have full access to the internet which I have content filtered. SOnicwall keeps telling me its not their device yet if I connect through anything else (straight to my ISP) it works fine. Can anyone help out with this problem or suggest another way of testing to ensure it is or is not the SOnicwall firewall.
