I manage a server thats been running fine for months.
Suddently, all the Outlook Anywhere users couldnt connect to Exchange over HTTPS.
If I go to https://server.company.com/Exchange
, it comes up with a certificate warning containing a random URL of www.ktdwvm554ydad2ht3sg.net
If I try the same but http://server.company.com/exchange
it works fine.
I've used wireshark and netstat to try to diagnose what is happening, but when I use https (port 443), wireshark receives nothing. I've double checked too.
I also checked the ADSL router to ensure the virtual port mapping hasnt been messed with, but its all fine.
Any ideas what could be happening with the port 443 traffic?
