Dear All, I have one exchange 2003 server, I want to trasit it into exchange 2007. I have done everything upto installation of exchange 2007 SP3 with new machine. After installing exchange 2007 co-exist with exchange 2003. I am unable to find IIS 7.0 in Administrative tools of Windows server 2008 R2 SP1 Even I try to search "inetmgr", but it is also not found from the server. When I am trying to load "OWA" it is showing as done in internet explorer. but it is not loading on the IE itself. My exchange 2003 legacy users are working fine right now. My exchange 2003 is running on Windows Server 2003 SP2 R2 32bit. Currently I have only one DC with a forest. and my DC's OS is also same like exchange 2003 OS. Please find attached screen shot for your further trouble shooting and help me to solve this problem. Bhavyang R Patwari https://www.mcpvirtualbusinesscard.com/vbcserver/bhavyangraj/profile

Hi, It might be a good idea to recreate the OWAVirtualdirectory or uninstall/install the CAS Role again.
