Today’s tip…

PowerShell Web Access (PWA) works off a "whitelist" security model whereby permissions must be granted for users to access machines.

PS C:\> Get-PswaAuthorizationRule

Id     RuleName      User          Destination

--     --------      ----          -----------

0      Rule 0        contoso\user1 SERVER1.contoso.com

The following command may be used for testing or troubleshooting purposes to allow all users to access all machines.

PS C:\> Add-PswaAuthorizationRule * * *

This can be very useful if you need a litmus test to determine if a whitelist configuration problem is responsible for "an authorization failure occurred" or other errors.
