Url works when pinging but causes UriFormatException

I have a mail server I'm trying to connect to with exchange web services. If I ping the server, it works, but it gets a UriFormatException when provided in code.

Urls that work in command prompt but fail in c#

Urls that can be parsed into URIs but fail to be pinged

I also tried adding \\ to the beginning but had no luck.

We do have a bit of a weird setup with connecting to our domain when on-network that I believe is what is causing http://myserver.mydomain.com to fail in ping. How can I turn the base url (without the http://) into a string that will be valid for a c# Uri?

Code:

var serverUrl = "myserver.mydomain.com"; //base string I'd like to use
_exchange.Url = new Uri(serverUrl); //causes UriFormatException:  Invalid URI: The format of the URI could not be determined.

To consturct Uri from host name use UriBuilder:

var builder = new UriBuilder();
builder.Host = "myserver.mydomain.com"; 
var uri = builder.Uri;

Note that what you call "uri" (myserver.mydomain.com) is actually "host name" or "DNS name" which is what get resolved to IP and than used to Ping. "http://myserver.mydomain.com" is absolute Uri for particular protocol (HTTP).
