Titel: Issue connecting MS Exchange Server  BeitragVerfasst am: 11.11.2006, 12:23 Uhr

My email at work is unfortunately routed through an MS Exchange server. Approximately 2 weeks ago, all 3 of my Kanotix installs cannot connect to the MS Exchange server either via a web browser or via Evolution (which uses a converter for the web interface). I have tried several different browsers (Firefox, Mozilla, Opera, IE under WINE, Konqueror) and none can connect. I've tried other Distros (Ubuntu, DSL) and they connect fine. I've turned off my firewall, no change. I cannot connect at work or at home.

I have a capture file from Wireshark and it appears that a packet is being dropped (see below). I assume my problem is a file update to something dealing with ssl or authentication, but do not know where to start.

Here is the capture of an attempt to connect to the web interface (IP address and MAC ID masked to protect the guilty):
