Directory searcher

I initially wrote a script to generate Outlook signatures in PowerShell, and now I want to turn it into a C# program with extra features like template building and customization, etc.

The beauty of the initial script is that you simply pass a user name to it, and it does the rest. Pulls the info, creates a directory structure, spits out HTML etc.

What I'm having trouble with is pulling the info from AD in C#. I've been trying to get to this with the DirectoryServices namespace. I think I have a basic grasp of how it's supposed to work, and what it's supposed to do, but I keep getting errors as if I'm missing something important like a type conversion, or how to initialize the data to be usable inside the app.

Here's my code, and I don't know what's wrong with it:

Console.Write("What User do you want properties for?:");
string usr = Console.ReadLine();

DirectoryEntry dir = new DirectoryEntry("OU=users,DC=domain,DC=com");
DirectorySearcher find = new DirectorySearcher(dir, "(&(objectClass=User)(enabled=true)(SAMAccountName=" + usr + "))");
find.PropertiesToLoad.Add("SAMAccountName");
find.PropertiesToLoad.Add("GivenName");
find.PropertiesToLoad.Add("Surname");
find.PropertiesToLoad.Add("StreetAddress");
find.PropertiesToLoad.Add("City");
find.PropertiesToLoad.Add("State");
find.PropertiesToLoad.Add("PostalCode");
find.PropertiesToLoad.Add("OfficePhone");
find.PropertiesToLoad.Add("HomePhone");
find.PropertiesToLoad.Add("Fax");
find.PropertiesToLoad.Add("EmailAddress");
find.PropertiesToLoad.Add("Pager");

Console.WriteLine(find.Filter);

SearchResult res = find.FindOne();

The error is around where I try to print to screen to ensure I have the right info. As shown here:

Console.Write(res);
Console.ReadLine();

Edit: Additional information.

The issue appears to be when executing 

SearchResult res = find.findOne();

Also the actual error is 

Unhandled Exception: System.Runtime.InteropServices.COMException: Unspecified Error

    at System.DirecoryServices.DirectorySearcher.FindOne()
    at ConsoleApplication1.Program.Main(String[] args)

Also, compiler output. I was initially under the impression that this was because the machine I'm coding on isn't part of the domain I'm checking against, but I've also been running the executable on a machine that is.

Include the protocol, server, and port in the path:

DirectoryEntry dir = new DirectoryEntry("LDAP://servername:port/OU=users,DC=domain,DC=com");
