I am rolling out the universal forwarders to my domain controllers. All was going well untill I started installing it on my 2008R2 domain controllers. The universla forwarder works fine on my 2k3 and 2008 boxes. On my 2008R2 servers the agent checks in but doews not send any events. It looks like it gets it config from the deployment server but then it can't connect. I found this in the splunkd.log: No connection could be made

I had something similar. To fix, I opened the Firewall settings on the Splunk Server and added the Splunk Receiver port (9911) and Splunk Admin Port (8000) to the allowed exceptions and all worked fine.
Changes were made to the indexer server. By default, outbound connections from the forwarder server do not normally need firewall changes. The indexer will need to have the scope for the forwarder as well as the ports in use.
Were your firewall changes done on the indexer or the universal forwarder?
Sounds like a networking problem.
The forwarder is saying that it cannot open a socket to your 10.x.x.x host on 9997.
Possibilities include:
You can probably rapidly rule out the client behavior by trying to telnet to that port from those systems. Likely, you will get the same error.
Same here, i am seeing this behavior on my 2008 systems
Does anyone know what the problem was? We are experiencing the same problem. The UF checks in but after a few hours, even 24 hours but eventually stops sending.
