Wireshark need help with analysis of capture file?
Posted on 2011-02-18
I have a user at a hotel, using the hotel's wireless, connecting via a vpn. When he opens Outlook 2003 he can't connect to our Exchange server (I think it's 5.5). Outlook displays connecting in the lower right hand corner of the display and it just sits there. Cache Mode is enabled and he has a 14 gb ost file.
I setup a capture at the firewall and opened it up in Wireshark.
In the Protocol column I see MAPI and in the Info column I see unknown?! request. The next row in the Protocol column I see MAPI and in the Info column I see [TCP Out-of-order] unknown?! request.
Seems to go on forever. Would someone provide an overview of what this means? I'd like to know if the problem is on the client or on the server , or on both. If you need additional info let me know.
