Hi,
I was trying to connect to report server (installed on my machine) from the virtual machine on which CRM is installed.(While creating a new organization using Deployment Manager MMC snap-in)
I was getting page not found error for the following url of the report server
http://servername/reportserver.
Later realized that it was because of the new anti virus tool that i had installed, the firewall was set enabled by default.
Disabled the firewall and then everything was fine.
Bye.
