First, I forgot the simple thing to do. Hit a command prompt on the server and flush your dns cache. Maybe something stuck in there.
5.5 uses the Windows settings for DNS lookups. So add your ISP to the properties for your network connection. I had this at old job and that fixed it for us. There is something odd about how windows looks up mx records. I have never been able to get an exact handle on it. > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] On > Behalf Of April Fleming > Sent: Friday, October 15, 2004 1:41 PM > To: Exchange Discussions > Subject: RE: network error during host resolution > > Sorry, not sure I understand.
