Hi, I installed Exchange 2010 doing a typical install into a domain running Exchange 2007. Susquent to the install complete users are being prompted to enter credentials continously for the new server. What steps can I take to prevent this occuring? Thanks, Adam

HI, Did you point new exchange 2010 cas server as Audiscover server in DNS ? You should change Host record and point the new server. regardsChinthaka Shameera | MCITP: EA | MCSE: M | http://howtoexchange.wordpress.com/

Hi Chinthaka, Post install of Exchange 2010 no additional step were undertaken. Pinging autodiscover resolves to the 2007 host. To resolve the annoyance for users I uninstalled 2010. However I would like to install it again and transition without interfering with the current 2007 installation. Regards, Adam
