Possible misconfiguration in the RDS broker settings, network issues, or service failures.

What to Check First

Verify RDS broker service status
Check network connectivity to the RDS broker
Ensure that the RDS licensing is valid and not expired

Fix Steps

Check the status of the RDS broker service
Ensure that the Remote Desktop Connection Broker service is running.
Safe to run: read-only
```
Get-Service -Name 'TermService'
```
Restart the RDS broker service if not running
If the service is not running, restart it to re-establish connections.
Changes system state: review before running
```
Restart-Service -Name 'TermService'
```
Check the RDS broker configuration
Verify the RDS broker settings in the Remote Desktop Services Manager.
Safe to run: read-only
```
Get-RDSessionHost -ConnectionBroker 'YourBrokerName'
```
Validate network connectivity to the RDS broker
Ping the RDS broker from a client machine to ensure connectivity.
Example pattern only. Adjust for your environment before running.
```
ping YourBrokerName
```
Check the Event Viewer for errors related to RDS
Look for any critical errors in the Event Viewer that may indicate issues.
Safe to run: read-only
```
Get-EventLog -LogName 'Application' -Newest 50 | Where-Object { $_.Source -eq 'TermService' }
```

Validation

Test user connections after performing each step to confirm resolution.

Logs to Check

Event Viewer under Application logs for TermService errors
RDS broker logs located at C:\Windows\System32\winevt\Logs\Microsoft-Windows-TerminalServices-RemoteConnectionManager%4Operational.evtx

Rollback and Escalation

If service restart fails, revert any recent changes to RDS configurations.

Escalate When

If the issue persists after all checks and fixes, escalate to the network team for connectivity issues.

Edge Cases

Check for firewall rules blocking RDS traffic.
Ensure that the licensing server is reachable and licensed.

Notes from the Field

Always verify the RDS licensing status as expired licenses can cause connection issues.
Document any changes made to the RDS configuration for future reference.
