I have tried to resolve the issues by using the recommendations provided by microsoft. To access the session host, your local PC must meet one of the following requirements:
- The local PC is Azure AD-joined to the same Azure AD tenant as the session host
- The local PC is hybrid Azure AD-joined to the same Azure AD tenant as the session host
- The local PC is running Windows 11 or Windows 10, version 2004 or later, and is Azure AD registered to the same Azure AD tenant as the session host
To enable access from Windows devices not joined to Azure AD. You need to add targetisaadjoined:i:1 as a custom RDP Property to the host pool.
Follow below steps to add targetisaadjoined:i:1 RDP property to the host pool:
- Login on Microsoft Azure portal using link https://portal.azure.com.
- Browse to Azure Virtual Desktop and then Find the Host pool.
- On the Left hand side, you will see RDP Properties.
- RDP Properties -> Then Find Advanced tab.
- In the RDP Properties box you need to enter a semicolon (;) and then type targetisaadjoined:i:1.
You can refer to below screenshot which shows targetisaadjoined:i:1 RDP property in a host pool.
