IIdentity id = WindowsIdentity.GetCurrent(); 
      WindowsIdentity winId = id as WindowsIdentity; 

      if (id == null) 
      { 
       CurrentUserEmail = "identity is not a windows identity"; 
       return; 
      } 

      var name = winId.Name; 

      string userInQuestion = name.Split('\\')[1]; 
      string myDomain = name.Split('\\')[0]; // this is the domain that the user is in 
      // the account that this program runs in should be authenticated in there      

      using (HostingEnvironment.Impersonate()) 
      { 
       DirectoryEntry entry = new DirectoryEntry("LDAP://" + myDomain); 
       DirectorySearcher adSearcher = new DirectorySearcher(entry); 

       adSearcher.SearchScope = SearchScope.Subtree; 
       adSearcher.Filter = "(&(objectClass=user)(samaccountname=" + userInQuestion + "))"; 
       SearchResult userObject = adSearcher.FindOne(); 
       if (userObject != null) 
       { 
        string[] props = new string[] {"mail"}; 
        foreach (string prop in props) 
        { //when it works set variable to CurrentUserEmail instead of txtDetailPrblem textbox 
         CurrentUserEmail = userObject.Properties[prop][0].ToString(); 
        } 
       } 

      }
