Hi,
One of our customers is having an issue with their remote desktop setup.
Back in August they upgraded their RDS environment from Windows server 2008 to Windows server 2019, and afterwards this issues began to happen frequently.
They didn´t have any issues before Windows server 2019,
Setup:
1 Broker, 1 Gateway, 1 web and 4 Session hosts
Windows server 2019 Version 1809
The issues can be 1 or 3 servers, it´s very random.
The issue occurs after the daily restart.
The issue can occur every day or once every month.
In this example, let´s say RDS01.
The issues is that some days users won´t be logged onto the session host.
So all users will be using RDS02, RDS03 and RDS04 and RDS01 will be empty.
RDS01 is running, we are able to RDP to it and everything looks OK.
Solution: remove RDS01 from collection (host servers) and add it again. Now users will be logged onto RDS01.
What we have tried:
Reinstall session host role on all RD session hosts.
Rejoined session hosts to the domain.
Checked network connectivity - no problem here.
We found an issue with the replication to one domain controller, we fixed it but it didn´t solve this issue.
Checked the domain controllers with dcdiag, active directory replication status and repadmin /showrepl in cmd - no issues.
In the event viewer, the following errors is created every day after the restart:
rds01: the processing of group policy failed because of lack of network connectivity to a domain controller
rds02: This computer was not able to set up a secure session with a domain controller in domain MESSAGE due to the following:
rds03 This computer was not able to set up a secure session with a domain controller in domain MESSAGE due to the following:
rds04 the processing of group policy failed because of lack of network connectivity to a domain controller
Do you have any ideas?
