the certificate is not from a trusted certifying authority
Please help!
I have a simple server that I have enabled RDP on at work. I go home, fire up Remote Desktop, type in a public IP address, log on with my credentials, and I'm in.
During the logon process, I get an alert like the one attached: "the certificate is not from a trusted certifying authority". If I go through the process of installing the certificate, I get the prompt "The server name on the certificate is incorrect".
I don't want to ignore the prompt (I have to explain the prompt to management). Is there a way I can get rid of it without having to buy an external certificate, setup an enterprise CA, or setting Remote Desktop to not warn me about it (advanced tab > server authentication option)? Can I safely ignore it, since I'm using an IP address that I know, and can be fairly certain it's not a man in the middle attack? I do have NLA enabled on the remote box.
The remote box is server 2012 and my home computer is Windows 7 with the latest version of Remote Desktop.
Thank you all, I appreciate any help I can get.

Self-signed certificates are never 'trusted'. You have to purchase a certificate from a reputable vendor to get it to be "from a trusted certifying authority". Only then will there be a certificate chain that leads back to a "trusted certifying authority".
Since you don't want to set up a proper certificate you can elect to ignore it. If the certificate changes you will have to agree to ignore it in the future.

Thank you for the responses, I appreciate them.
My understanding is that the point of the prompt is to ultimately help prevent man-in-the-middle attacks. Since I am using NLA and am using an IP address to connect, is a man-in-the-middle still possible, or highly unlikely?

Thanks. Is there a way I can visually tell if the information on the prompt is actually legitimate (spot if something is wrong)?
Certificate error messages normally give the details of their complaint. A valid certificate will show in the address bar where you can click on it to get more info about it.
