Authenticate with windows domain

[pascalzieglerenvision]

Hey,

How would y'all implement it if you want to authenticate per windows user name + password without the need to acually let the user type in the information everytime.
My code trying it on my own (without teamcitysharp) which failed:

var webRequest = (HttpWebRequest)WebRequest.Create("URL");
NetworkCredential creditsDefault = CredentialCache.DefaultNetworkCredentials;
NetworkCredential myCredits = new NetworkCredential("pascal.ziegler", "Password");

        Console.WriteLine("Default Credits: " + creditsDefault.Domain + creditsDefault.UserName + creditsDefault.Password);
        Console.WriteLine("My Credits: " + myCredits.Domain + myCredits.UserName + myCredits.Password);

        webRequest.Credentials = creditsDefault;
        webRequest.GetResponse();

using myCredits works fine. i get access and get the information in return. using creditsDefault gives me a 401 access denied. the server log seems to be able to read my user name but not my password:

Hello pascal,
You can use HttpClient instead of WebClient.

var handler = new HttpClientHandler() { UseDefaultCredentials = true };
httpClient = new HttpClient(handler);

You can find many examples when googling.
