Accessing the console remotely causes 401 Unauthorized error page. IIS logs show 401 1 (401.1) error.
Windows Security event logs show successful authentication from remote IP
Other problem could be:
Continually prompted for credentials when trying to get into the console. This happens both at the server and from a remote console.
Windows Authentication does not seem to properly function between IIS and Windows.
This seems to be an issue caused by IIS settings to use kernel mode authentication.
Disable the kernel mode authentication for Windows Authentication on the Altiris website.
Note! Turning off kernel mode authentication will break IT Analytics. Microsoft KB http://support.microsoft.com/kb/2749007 offers two workarounds to this problem - "disable Pre-Authentication in Internet Explorer, or turn off Kernel Mode Authentication for the IIS Web application".
To "disable Pre-Authentication in Internet Explorer" add the following registry value to the computer that you are opening the console on:
HKEY_CURRENT_USER/Software/Microsoft/Windows/CurrentVersion/Internet Settings/ Value Name: DisableNTLMPreAuth Data Type: REG_DWORD Value: 1
