This is my code!

public static string ConnectAcitveDirectory(string groupName, string domainName, string serverName, string adminUserName, string queryUserName, string queryPassword)
       {
           try
           {
               //DirectoryEntry connectionAD = new DirectoryEntry(serverName, queryUserName, queryPassword);
               //DirectorySearcher search = new DirectorySearcher(connectionAD);
               //search.PageSize = 1001;
               //search.Filter = "(&(objectClass=user)(SAMAccountName=" + adminUserName + "))";
               //SearchResultCollection result = search.FindAll();

               //if (result.Count > 0)
               //{
               //    foreach (SearchResult item in result)
               //    {
               //        if (item.Properties["SAMAccountName"].Count > 0
               //                && Convert.ToString(item.Properties["distinguishedName"][0]).Contains("OU=" + groupName))
               //            return "Active Directory is all set up! User was authenticated";
               //    }
               //}

               using (PrincipalContext domainContext = new PrincipalContext(ContextType.Domain, serverName, domainName + "\\" + queryUserName, queryPassword))
               {
                   using (UserPrincipal foundUser = UserPrincipal.FindByIdentity(domainContext, IdentityType.SamAccountName, adminUserName))
                   {
                       if (foundUser != null )
                           return "user found";
                       else
                           return "no user!;
                   }
               }
           }
           catch (Exception ex)
           {
               return ex.ToString();
           }
       }

Both the above codes (commented and uncommented code) would work one at a time. They work in my local system, in a console application.

But if I move the console application's EXE file to a server, where Active Directory is installed, it would not work. Instead throws below error.

--------------------------------------------------------------------------------------
System.DirectoryServices.DirectoryServicesCOMException (0x8007052E): The user name or password is incorrect. at System.DirectoryServices.DirectoryEntry.Bind(Boolean throwIfFail) at System.DirectoryServices.DirectoryEntry.Bind() at System.DirectoryServices.DirectoryEntry.get_AdsObject() at System.DirectoryServices.DirectorySearcher.FindAll(Boolean findMoreThanOne) at tap.dom.usr.Authentication.ConnectAcitveDirectory(String groupName, String domainName, String serverName, String adminUserName, String queryUserName, String queryPassword)

Any idea guys? Please let me know if you have any solution for this.

Thank you,
