Running Windows 2008 Server R2.
I'm running an Application that runs on 2 servers, ServerA and ServerB. ServerA is Active and ServerB is passive. There is replication of data from ServerA > ServerB.
Recently Ive noticed that there are replication errors within the App. The vendor says this could be due to data not reaching ServerB in a timely manner.
I'd like to see if there are any NIC or network related issues. Is this possible via Perfmon? I have asked the Cisco team to check out the switchport too, but it would be useful to have some info from the server side.
