I’m attempting to setup a Windows 2022 RDS Standard Deployment for Session Hosting. The layout is as follows:
RDS01 – RDS Connection Broker and Web Access
TS02 – RDS Session Host
TS03 – RDS Session Host
The domain these servers are part of has (1) Windows 2008 Server and (2) Windows 2022 Servers acting as DCs. The domain is running Windows 2003 Functional Level.
All servers are on a single routed network with no firewall between them. All DNS A and PTR records for all servers exist and resolve on all hosts. All servers can be pinged by each other. In other words, there are no network connectivity issues.
I’ve setup the RDS deployment several times w/ the same results.
The Issue
I can login via the RDWeb interface on RDS01 from a Win10 desktop and connect to the published RDP desktop without issue (i.e. no error messages to the user) and no errors in the logs. When I try to directly RDP to RDS01, I successfully authenticate as
a user (per the sự kiện log) but get an error stating that the user doesn’t have access to the system. In the sự kiện log I get sự kiện id 1306 with the message of “Remote Desktop Connection Broker Client failed to redirect the user <domain><test
user>. Error: NULL”.

If I RDP to RDS01 as an administrator, I get the same error message but the RDP session opens and presents the desktop on RDS01.
I can RDP directly to TS02 or TS03 and login as a user and open the RDP session. Redirection to some degree appears to be working in that I can disconnect a user session from TS02 and RDP to TS03 and the session is redirected back to TS02. The sự kiện
logs on RDS01 record this happening as well.
What I’ve tried already
1. In searching this sự kiện 1306 issue, I found several posts with this exact same behavior in WS 2012/R2. Most “solutions” suggested point to the fact that the RDS Session Broker doesn’t have sufficient authority to look up the users AD group
membership via the tokenGroupsGlobalAndUniversal attribute or AuthzInitializeContextFromSid API function which leverages the tokenGroupsGlobalAndUniversal attribute. (Example: https://social.technet.microsoft.com/Forums/windowsserver/en-US/29733a87-dbda-47bc-8b37-6eeac5ab5a0a/2012-rds-nonadministrators-can-not-access-vdi-pool?forum=winserverTS#97d883f1-7a64-4d02-9492-309638f92e79
)
The service is running as “Network Service” which does have network access via the Computer Object’s authority in AD. So following Microsoft’s instructions (https://tư vấn.microsoft.com/en-us/kb/331951), I’ve added RDS01 to both the Windows
Authorization Access Group and Pre-Windows 2000 Compatibility Access groups and rebooted RDS01 with the same results.
2. I’ve verified the Windows Authorization Access Group has rights to read the tokenGroupsGlobalAndUniversal property/attribute on my test users and the computer objects of the servers.
3. I’ve setup an AD Service account following Microsoft’s instructions (https://tư vấn.microsoft.com/en-us/kb/842423) with a similarly described access issue. The service account user was added to the Windows Authorization Access Group. This was
unsuccessfully as well w/ the same sự kiện 1306 error.
4. I ran the following powershell commands to verify access of the Connection Broker to the OU (https://technet.microsoft.com/en-us/library/jj215512.aspx#)
Test-RDOUAccess -Domain [redacted.domain] -OU “Computers” -ConnectionBroker rds01.[redacted.domain] -verbose
This failed so I ran the following to grant access
Grant-RDOUAccess -Domain watsons.local -OU “Computers” -ConnectionBroker rds01.watsons.local -verbose
The Test-RDOUAccess then succeeded.
I repeated this for the OUs that contained the users and the server computer objects.
I’ve disabled all GPOs to ensure there’s no conflicts but have seen no change in the behavior or error messages.
With all that, I’ve exhausted every option that I can find to resolve this error to gain the expected functionality. As a work around for the moment, I’ve setup a round-robin DNS A record that points to TS02 and TS03 w/ a very short TTL. This gives
the test users the ability to login and atleast test the desktop functionality.
Sorry for being so long winded with this but I thought it better to put all the cards on the table.
I’m open to any and all suggestions.
Thx!

Hi,
For the problem, I have tested for this on Windows Server 2022.
For the RD Connection Broker do not redirect the session to RDSH in a new RDS environment, you need configure the default collection on RDCB in registry.
You should create the registry value
DefaultTsvUrlunder the path below with
tsv://MS Terminal Services Plugin.1.<collection alias>
on RDCB.
HKLMSYSTEMCurrentControlSetControlTerminal ServerClusterSettings
For the value, you could find it in Event Viewer on RDCB like below.
Note: you should make back up before modifying registry.
Here is a similar thread below for your reference.

the last 2 days i have noted that our one beta user, is trying to connect in the morning and it connects to the actual RDCB instead of the farm behind it.
They are likely just opening up the RDP client instead of using an icon file or RDWeb as the client doesn’t know that about the LB entry. Which looks like this:
Text
loadbalanceinfo:s:tsv://MS Terminal Services Plugin.1.SesssionHost
Have you watched this user try to login?

the client is using a thin client so there is a setting for the broker that then shows them the Collection and allows them to log in.

Since this was in beta and not production i ended up rebuilding the entire server farm again and i have not had any issues since. i know that is not the answer you are looking for but i never got it working without that.

We were having similar issue with WSrv 2022 RDHS (single server) after a power outage (dirty shutdown).
As described inhttp://blog.ronnypot.nl/?p.=1013, the error sometimes happens when (1) you haven’t configured a collection, or (2) the collection configuration becomes corrupt. Solution is to recreate the collection. If you have a lot of apps (or special settings), could probably make a script based onhttps://stackoverflow.com/questions/25518071/powershell-re-create-rds-remote-apps-by-loopingto persist the RemoteApps list and settings to a CSV
, delete it, and then recreate the collection.
In our case, we made some changes to the collection using the UI, and then rebooted the server, and it is now functional.

Remote Desktop Connection Broker Client failed while getting redirection packet from Connection Broker. User : Error: Remote Desktop Connection Broker is not ready for RPC communication.
Posted on 11th October 2022 by
I was getting this in my sự kiện log and users could no longer connect to RDS when trialling it –
Event ID – 1296
Remote Desktop Connection Broker Client failed while getting redirection packet from Connection Broker.
User : DOMAINUSER
Error: Remote Desktop Connection Broker is not ready for RPC communication.
and then
Event ID – 1306
Remote Desktop Connection Broker Client failed to redirect the user DOMAINUSER.
Error: NULL
I found the Fix for me was –
If you edit the properties of your Session Collection, click on the Security on the left. There is a setting for Security Layer. By default it is Negotiate. Try toset it to RDP Security Layer
My users could then connect again, i made the change in group policy for all TS (RDS) servers
– Computer ConfigurationAdministrative TemplatesWindows ComponentsRemote Desktop ServicesRemote Desktop Session HostSecurity
– Edit ‘Require use of specific security layer from rermote (RDP) connections to Security Layer-RDP
