We've a Windows Event Collector in DOMAIN1. DOMAIN1 and DOMAIN2 have a two-way transitive forest trust. Events from sources in D1 are forwarding fine to the WEC in D1.
D2 is setup to communicate to the same FQDN subscription manager over http/5985 (Server=http://server1.domain1.com:5985/wsman/SubscriptionManager/WEC,Refresh=60). Source initiated event collection. Port 5985 is open and listening from D2 machines through WEC in D1.
Machines in D2 are getting this in their Eventlog-ForwardingPlugin Operational logs
The forwarder is having a problem communicating with subscription manager at address http://wec1.domain1.com:5985/wsman/SubscriptionManager/WEC. Error code is 2150858909 and Error Message is <f:WSManFault xmlns:f="http://schemas.microsoft.com/wbem/wsman/1/wsmanfault" Code="2150858909" Machine="server1.domain2.com"><f:Message>WinRM cannot process the request. The following error with errorcode 0xc0000413 occurred while using Kerberos authentication: An unknown security error occurred.
Possible causes are:
-The user name or password specified are invalid.
-Kerberos is used when no authentication method and no user name are specified.
-Kerberos accepts domain user names, but not local user names.
-The Service Principal Name (SPN) for the remote computer name and port does not exist.
-The client and remote computers are in different domains and there is no trust between the two domains.
After checking for the above issues, try the following:
-Check the Event Viewer for events related to authentication.
-Change the authentication method; add the destination computer to the WinRM TrustedHosts configuration setting or use HTTPS transport.
Note that computers in the TrustedHosts list might not be authenticated.
-For more information about WinRM configuration, run the following command: winrm help config. </f:Message></f:WSManFault>.

I don't know enough about kerberos to know if tickets from D2 can be used in D1 or somehow made to. Anyone got any ideas? I can't find much about this exact issue and WEF.
