Outlook 2007 loosing connection to Exchange 2003 - DNS?

Posted on 2011-05-04
Last Modified: 2012-05-11
I have Exchange 2003 running on Windows 2003 (DC).  Occasionally and randomly Outlook 2007 clients loose connection to the Exchange server.  When this happens I cannot ping the server name but I can ping the IP address.  This only seems to happen to the exchange server.  I can still access shares and ping machine names of other servers.  This must be a DNS issue but I can’t seem to find the answer.

    I forgot to mention when I do an ipconfig /release /renew the issue resolves itself.

    One more update if I do ipconfig /flushdns it also seems to resolve the issue

    Is the Client using only the AD/DNS in its TCP/IP Specs on the nic?

    Is the DC using only itself and maybe a second DC for the only DNS in the TCP/IP Specs?

    This was a DNS Server assignment issue.  I had set an external dns server in my dhcp scope.  Setting it back to my internal dns server resolver the issue

    Actually just just did what I told you to do.  Whether DNS in the TCP/IP specs was assigned statically or via DHCP doesn't really matter
