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.
