SCCM client does not appear in console. Failed to receive buffer from server with err=0x80090304

If you happen to be in situation when seemingly your SCCM client is working fine, but does not appear in SCCM console, then check CcmNotificationAgent.log
If you see these lines:

Failed to receive buffer from server with err=0x80090304.
Failed to signin bgb client with error = 80090304.


The probably there is conflict with client GUIDs. And you can resolve it with following actions on SCCM client:

  1. net stop ccmexec
  2. certutil –delstore SMS SMS
  3. Rename c:\windows\SMSCFG.INI TO c:\windows\SMSCFG.INI.old
  4. net start ccmexec

Fix "The Active Directory Domain Controllers required to find the selected objects in the following domains are not available" error in AD trust scenario

Hello,

If you have set up an Active Directory forest trust but you cannot browse users in trusted domain because of error "The Active Directory Domain Controllers required to find the selected objects in the following domains are not available", then most likely you have not configured networks ports correctly.


Usually when I configure AD trusts, I take this article https://docs.microsoft.com/en-us/previous-versions/windows/it-pro/windows-server-2008-R2-and-2008/dd772723(v=ws.10) to allow necessary firewall ports.

In addition to ports mentioned in this article we also had to open TCP port 135 to be able to browse users in trusted forest.
I don't know exactly but I suspect that this was due to fact that trusted forest was still using Windows Server 2003 Forest functional level.
