Hi Everyone, I'm building a lab to centralize Windows Event Logs before sending them to Splunk. The objective is to collect Windows event logs from multiple Windows servers at a single Windows Event Collector (WEC), then forward the centralized logs to Splunk using a Universal Forwarder. Lab Architecture AWS VPC   WINSRC01 (Windows Server 2022) Event Source │ │ WINSRC02 (Windows Server 2022) Event Source │ │ Windows Event Forwarding (WEF) │ ▼ WEC01 (Windows Server 2022) Windows Event Collector (WEC) + Splunk Universal Forwarder │ │ ▼ Splunk Heavy Forwarder (RedHat) Splunk Enterprise 9.4.1 Objective WINSRC01 and WINSRC02 should forward their Windows Event Logs (Application, Security, and System) to WEC01 using Windows Event Forwarding (WEF). WEC01 should collect all forwarded events in the Forwarded Events log. A Splunk Universal Forwarder installed on WEC01 should monitor the Forwarded Events log and forward the data to a Splunk Heavy Forwarder running on Redhat. This design reduces the number of Splunk forwarders and provides a centralized Windows event collection point.   Configuration Performed Deployed three Windows Server 2022 EC2 instances in the same AWS VPC. Configured one server as the Windows Event Collector (WEC01). Configured the other two servers as event source computers. Enabled WinRM and PowerShell remoting on all servers. Successfully initialized the Windows Event Collector using:   Powershell wecutil qc   Verified WinRM connectivity between the collector and both source servers using Test-WSMan. Confirmed TCP port 5985 is reachable. Configured Windows Firewall appropriately. Problem Faced Since the servers are standalone workgroup machines (not joined to Active Directory), we encountered multiple issues while configuring Windows Event Forwarding. 1. Collector-Initiated Subscription When creating a Collector-Initiated subscription, clicking Select Computers failed because the dialog searches Active Directory for computer objects. Since our servers are not domain joined, Windows could not locate WINSRC01 or WINSRC02. 2. Source-Initiated Subscription We then switched to a Source-Initiated subscription. The Event Viewer GUI would not allow us to save the subscription correctly, so we created it using: wecutil cs WindowsServerLogs.xml The subscription was created successfully, but it never became active. Running: cmd wecutil gr WindowsServerLogs returned: RunTimeStatus : Inactive LastError : 1337 ErrorMessage : The security ID structure is invalid. The subscription creation command also reported: The subscription is saved successfully, but it can't be activated at this time. Error = 0x3ae8 The subscription fails to activate. Additional Observation Running: cmd wecutil gs WindowsServerLogs shows: AllowedSourceDomainComputers: O:NSG:NSD:(A;;GA;;;DC)(A;;GA;;;NS) which appears to be a security descriptor intended for domain computers, even though our environment consists entirely of workgroup servers. Question Has anyone successfully implemented Windows Event Forwarding in a standalone workgroup environment using the architecture shown above? Specifically: Is Source-Initiated WEF over HTTP supported without Active Directory? Does the LastError: 1337 (The security ID structure is invalid) indicate that the collector is expecting domain-based security identifiers? Is HTTPS with certificates required for workgroup-based Source-Initiated subscriptions? Would it be better to deploy Active Directory and use Kerberos authentication for this architecture? Any guidance or working examples would be greatly appreciated. Thank you! ... View more
