Two errors for Exchange 2010

Recently the company wants to build mail server

In the process of encountering two problems, recorded. Warning

1, login interface can come out but no matter what input is garbled. Problem reason authentication is problematic.

: Change to this, and then restart IIS.

2 map to the server with the routing port. The root directory of the Web site can be accessed, but the OWA directory cannot be accessed,

The workaround is accessed using the following URL https://ip:port/owa/auth/logon.aspx

So the login interface can come out but may click on the login after the page cannot be displayed, the URL becomes so https://ip/owa/manually change the URL to https://ip:port/owa/can login
