activesync/exchange issue

[djscrew]

Well activesync was working fine with exchange for a while. We moved DNS over to a new server and for other reasons had to move DNS back. None of the actual DNS records changed. Well now my treo can't sync with the server. We've got a few people in the office with WM6 phones that aren't having any problems. I can't even browse to outlook web access on my phone, but it works fine from any PC. Activesync error: "The server could not be reached. Please verify the server name." support code: 0x80072EE7

Thanks for any help that you can provide.
