I have a Windows 2008 R2 Server which I moved to a new location last weekend. After configuring the DNS server (there is an Active directory installed as well) I get this dialog "Windows Security" every now and then, especially when trying to interface towards the Interwebs...
It has a message.
Connecting to wpad.domain.com
Now, any ideas what this is and how I can get rid of it?
wpad.yourdomain.com is the internet explorer proxy autodetect. You should be able to make it go away by turning proxy autodetection off in group policy.
