    i need to get some information about users from the active directory. But before i do that the user must specify a domain name.

    Which is the fastest way to check if the provided domain name is valid and a connection to the ad is possible?

    You may want to consider making a quick HttpRequest just using the HEAD method (to avoid pulling all of the content) and checking the Response to see if it was valid : 

    HttpWebRequest request = (HttpWebRequest) WebRequest.Create(yourUrl);
    request.Timeout = 15000; //Allow 15 seconds to process the Request otherwise timeout
    request.Method = "HEAD";
        using (HttpWebResponse response = (HttpWebResponse)request.GetResponse())
            return response.StatusCode == HttpStatusCode.OK;
    catch (WebException)
        return false;

    as per the C# Wizard Jon Skeet's suggestion.
