Ошибки при размещении сайта asp.net framework на iis

Я создал простой сайт на asp.net framework, в котором есть стандартная проверка подлинности пользователей, то есть регистрация, но я добавил в нее нужные мне поля и направил ее на бд sql server, а не в локальную бд, как это было раньше.

Сейчас при попытки входа или регистрации почему то во первых выполняется такой вот запрос в адресной строке :

/Account/Login?ReturnUrl=%2FAccount%2FLogin%3FReturnUrl%3D%252FAccount%252FLogin%253FReturnUrl%253D%25252FAccount%25252FLogin%25253FReturnUrl%25253D%2525252FAccount%2525252FLogin%2525253FReturnUrl%2525253D%252525252FAccount%252525252FLogin%252525253FReturnUrl%252525253D%25252525252FAccount%25252525252FLogin%25252525253FReturnUrl%25252525253D%2525252525252FAccount%2525252525252FLogin%2525252525253FReturnUrl%2525252525253D%252525252525252FAccount%252525252525252FLogin%252525252525253FReturnUrl%25

И это не весь запрос, там вот так повторяясь идет около 4000 симоволов. а на страничке в опере выпадает такая ошибка:

Если через минуту обновить страницу, то появляется вот такая ошибка:

Я нашел где то на форуме ответ, что надо выполнить следующее

Для Интернет-информационных услуг (IIS) 6.0 и более поздних, ключи реестра MaxFieldLength и MaxRequestBytes расположены в следующем подключе:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\HTTP\Parameters

Я вроде задал это:

Но все равно все также.

Вот лог iis сервера:

Подскажите, как это исправить? надо как то разрешить длинный такой запрос? или это косяк в коде и запрос не должен быть такого размера? но это стандартная Asp регистрация, созданная автоматически. Помогите, пожалуйста, устранить ошибку
