  • Windows 7 can't solve hostnames in domain

    I have a new Dell with Windows 7 32-bit joined to my domain (work domain). My problem: I can ping all the hostnames inside my LAN, but when I try to ping our corporate mail server using the hostname it does not resolve it. I can ping the mail server IP address and get a reply. Is there a security setting I need to turn off? My Windows XP workstations work perfectly.
    I have McAfee Enterprise Anti-virus and Windows Firewall turn on.
    Thanks in advance for your replies.

    Where is the corporate mail server - in a DMZ or on the Internet?

    Please post the result of an ipconfig /all from the Windows 7 PC and let us know the IP (anonymised as appropriate) of the mail server.

    What are you using for DNS?

      you can test what mode the firewall is, i have had a similar issue when it was in public network mode.

        Thanks to everyone that posted a reply. The problem was fixed by appending an extra DNS suffix and adding a corporate DNS server ip address.
