Weve been using Exchange 2003 (Standard) and Outlook 2007 for almost a year without any mayor issues. Our environment: workstations/laptops using Vista and XP. Also Windows mobile phones connected to our Exchange server.
Recently we started to notice that one of our servers (www.ourdomainname.com
) located in another location, started to receive every 5 minutes or so, a request for page autodiscovery/autodiscover
y.xml. The message looks like this:
OURDOMAINNAME.COM:  HTTP Page autodiscover/autodiscover.
xml not found 404 error IP: ourpublicIPaddress Visit No: 1507 @ 3/27/2009 11:27:51 AM
We never used in our environment Exchange 2007 and therefore, we do not have CAS role nor A record in our DNS for autodiscovery.
We noticed that the message is received mostly during office hours (between 9 and 5pm) which indicate that it is generated from one of the workstations in our office. My question: Is there any way to cancel the Autodiscovery request in Outlook? Any ideas how to detect the culprit workstation?
