How to use PuTTY to test SMTP on an email server.

If you have not already, you can download PuTTY from putty.org

Once you open PuTTY you can input the mail server name or IP address you are attempting to connect to into the Host Name field. Then update the port to 25 and the connection type to "Telnet".

When you click connect you should see something like this:

Other responses:

Windows Server, Remote Desktop: An internal error has occurred, Hyper-V Guest OS

This can happen for several reasons, mostly related to too much bogus traffic hitting your RDP port. It is best practice to only allow RDP access to a limited set of static IP's, only access via firewall or if the other two options are not possible change the default port for RDP access to help limit default bogus traffic.

With that said, the quickest way to solve this problem without a reboot is to simple disable the network adapter and reenable it.

Step by Step:

  • Login to your Hyper-V manager
  • Connect to the Guest VM in question
  • Open the network manager and change adapter settings or Control Panel\Network and Internet\Network Connections
  • Once on this screen simply right click the adapter and disable, then reenable.

Thats it, your issue should now be solved.
