Hi Md. Nasir Uddin,
Thanks for sharing the details. Based on the error you provided:
Event ID: 105
The forwarder is having a problem communicating with subscription manager at address http://ADDS-02.mylab.local:5985/wsman/SubscriptionManager/WEC.
Error code: 2150859027
Message: The WinRM client sent a request to an HTTP server and got a response saying the requested HTTP URL was not available.
This means the forwarder cannot reach the Windows Event Collector (WEC) endpoint over WinRM. The error usually occurs when:
- The collector does not have a proper WinRM listener for HTTP (5985) or HTTPS (5986).
- The subscription URL in the GPO is incorrect.
- The Windows Event Collector service is not running.
- Firewall or GPO is blocking WinRM traffic.
I managed to find a few solutions:
Verify WinRM Listener on Collector
Run this on the collector server:
winrm enumerate winrm/config/listener
- You should see an HTTP listener on port 5985 or HTTPS on 5986.
- If missing, create one:
winrm quickconfig
Check WEC Service
Ensure the Windows Event Collector service is running:
Get-Service Wecsvc
If not running:
Start-Service Wecsvc
Validate Subscription
Check if the subscription exists and is active:
wecutil gs <SubscriptionName>
Test Connectivity from Forwarder
On the forwarder (AD server):
winrm id -r:http://ADDS-02.mylab.local:5985
- If this fails, the issue is network/firewall or listener configuration.
Firewall & GPO
- Enable Windows Remote Management (HTTP-In) rule on the collector.
- If using HTTPS, ensure the certificate is valid and trusted.
- Confirm the GPO for WEF is applied:
gpresult /r
Restart Services
After fixing configuration:
Restart-Service Wecsvc
The error occurs because the forwarder cannot reach the WEC endpoint over WinRM. By ensuring:
- WinRM listener exists,
- WEC service is running,
- Firewall allows traffic,
- Subscription URL is correct,
you restore communication between forwarder and collector.
For more detail, you can check these links out when you have the time:
- Configure Windows Event Forwarding
- WinRM Troubleshooting Guide
- Event ID 105 Details
- Events are not forwarded if the collector is running Windows Server
- Events logs are not collected but event collection subscriptions are active
I know this is a lot of steps but please do try them out when you get the chance.
Let me know if you still see Event ID 105 after these steps or if logs start arriving at the collector.
