Networking and Exchange, well this can cause issues upon issues and log events you might have not seen before.

For example, on a customer server, the following 3x event ID’s were logged every 10-15 minutes:

  • 2501
  • 2601
  • 2604

Here are screenshots of each error:

From the server, you can ping the network, other servers can ping this server but there is an underlying network issue.

Some steps you can do to fix this:

  • Live migrate the VM(if its a VM) to another host and do a reboot.
  • Check the DNS settings on the server and make sure the main NIC is set under the binding order correctly.
  • Register DNS on the server by using the ipconfig /registerdns command.

Hope it helps.
