Hi guys,

I have a windows 2008 server (it's a secondary DC) with exchange 2007 installed.
This box is popping approx every 5 mins

I ran auto discovery, I have modified many different setting  (like owa, oab) in the client access under the server tab, but still is popping.  for some users it disappears after a few seconds with out press any key for other it never disappears and despite  they type the password and user name keep showing up.

 pop up

Hi mate,

I changed the authentication mode, I matched Domain policies with local policies according the doc above, I tried NTLM V1, V2 etc....at the end it didnt work.

any ideas?
What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

As mentioned have a look at the article created by demazter: He has written a guide on how to resolve this issue here: http://www.experts-exchange.com/Software/Server_Software/Email_Servers/Exchange/A_2300-Outlook-continually-prompting-for-username-and-password.html Although the Article states that SP2 for Exchange should be installed it should now change to SP3
