Network access message

» Microsoft ISA Server 2006/2004/2000 (Часть III)

Всё проверил . учётки не заблокированы. Сделал Reset Account для учётных записей компьютеров, сбросил пароли на пользователях, проверил сроки жизни Account-ов, всё в норме.

Что-то происходит с Аутентификацией клиентов.

Ещё меня смущает, что в панели наблюдения пишет «Службы каталогов AD Не задан»
Прописал в настройках серверы LDAP, не помогло, хотя раньше и без этих настроек работало.

Народ подскажите, есть isa 2004.
при попытке зайти на сайт https://yyy.xxx.ru:1777/ вывалиается ошибка

Network Access Message: The page cannot be displayed

Technical Information (for Support personnel)

Цитата: ssl в исе приучен на 443
Ну он как бы не только в исе приучен на 443 порт. Это какой-никакой, но стандарт.
Сделай себе новый listener и укажи ему слушать 1777 порт.

Уважаемые админы!
Подскажите плиззз! У меня стоит ISA 2006.

1. Где и как сделать так чтобы заходя удаленно на шлюз Я автоматом попадал на другой ккомп той же сети??

2. Ткните пальцем где именно открываются порты (диапозоны)?

так вроде все работает)

P.S.
Первый опыт общения с исой.

Вопрос возник.
Иса 2006, екстернал-интернал. NAT+firewall соот-но. Иса в домене, всё вроде работает. Тут подняли VPN сервер на ней же что бы иса могла принимать соеденения клиентов.
Возникл трабл с обработкой ГП. Начал мониторить, прикинулась интересная фича: как только иса пытаеться лезть за каким-н шаблоном ГП на DC по имени \ sysvol и соот-но по протоколу NetBIOS session (139 outbound) вместо внутреннего ip исы (который входит в интернаял) она почему то испольщует ip RRAS сервера и соот-но в лог вписывается запрещающеее правило по этому коннекту (при чём с пустым полем «правило):
Тип журнала: Служба межсетевого экрана
Состояние:
Правило:
Источник: Локальный компьютер (ip_RRAS:29829)
Назначение: Внутренняя (IP_DC:139)
Протокол: Сеанс NetBios
Пользователь:
Дополнительные сведения
Передано байтов: 0 Получено байтов: 0
Время обработки: 0ms Исходный IP-адрес клиента: ip_RRAS

Если напрямую попытаться зайти на шару контроллера через его имя (а не через сопоставление домена (\ ) то всё работает нормально, все файлы ГП видны. По доменному имени — нет.

Кто-н сталкивался? куда копать?

PS ес-но в системных рулах нетбиос разрешён с локал хоста в интернал, так же в нас-ка адвансета (сетевых) интернал стоит первым интерфейсом.

se111
Не помогло.

Народ. А вообще в ISA 2006 в приципе можно как-то разрешить отвечать на бродкасты с определенного ip?

Может быть кто-то сталкивался с такой проблемой .

ISA сервер 2006.
Пользователи не проходят аутоинтефикацию, блокируется доступ в Internet, Net Share, RDP.

MGrom
информативный вопрос Машина не едет, почему?

Что пытается вылезть в инет? IE? Аутентификация доменна? (АД есть) FWC ставил? И .т.д и т.п. Спарвка рулит по простым вопросам если что.

Имеем следующую ситуацию
1. SBS 2003 R2 — со всеми обновлениями.
2. ISA 2004 — опять-таки, со всеми обновлениями.
3. Все клиенты — SecureNAT

ПРОБЛЕМА.
Внутренние пользователи не могут обращаться по FTP к внешним FTP серверам.

ПОДРОБНОЕ ОПИСАНИЕ проблемы.
1. FTP Access filter — разрещен и используется в описании протокола FTP
— при использовании ftp.exe на любой из клиентских машин после ввода имени пользователя получаем сообщение ПОДКЛЮЧЕНИЕ РАЗОРВАНО УДАЛЕННЫМ УЗЛОМ.
— при использовании, например, totalcommander (режим — пассивный или активный — не важно) получаем сообщение OFFLINE и предложение снова ввести имя.

2. FTP Access filter — разрещен но НЕ используется в описании протокола FTP
— при использовании ftp.exe . равно как и Total Commander (режим неважен)
получаем сообщение PORT COMMAND FAILED.
Что, в общем, и не удивительно.

ВОПРОСЫ
1. Как разрешить выход по FTP в активном режиме?
2. Как настроить ISA для пассивного режима FTP?

У меня была похожая проблема но мне удалось ее решить небольшой програмкой ISAtrpe..

но вот загадка.. этой проблемы не наблюдается если на компьютере стоит firewall client.

Объясните несведующему почему через FWC все работает т.е. сайты открываются по https как на стандартный 443 порт так и на любой другой порт, а для клиентов прокси нужно добавлять нестандартный порт в ssl чтобы работало

В одном случае работает туннель наружу, а в другом вэб-фильтр — вот его и надо подкрутить.

Т.е. это искать в настройках web фильтра?

В одном случае работает туннель наружу, а в другом вэб-фильтр — вот его и надо подкрутить.

Можно по-подробней пояснить.. для случая с FWC и случая с прокси

А что подробнее? Прокси принимает запросы от клиентов на порт 8080 (по умолчанию) и пропускает прямо через веб-фильтр. FWC стоит на клиенте, перехватает сокеты (если приложение работает не через сокеты, то FWC его не обслуживает) и направляет трафик (любые протоколы не только HTTP(S)) на порт 1723 ISA сервера, а тот оптравляет его дальше (при этом HTTP(S) трафик по умолчанию заворачивается на веб-фильтр, но это можно отключить).

По умолчанию веб-фильтр считает, что HTTP(S) на порт 443. Если нужно использовать другие порты, то веб-фильтр нужно сконфигурировать.

7 Ways To Fix “Your Network Access Was Interrupted Access 2019/2016/2013” Error

Summary: Looking for the fixes to resolve MS Access Error 3043 which displays error message like “Your network access was interrupted. To continue close the database and then open it again”? If yes, then don’t go anywhere as here you will get the most suitable fixes to resolve this issue.

Access Database Error 3043 is basically an error message that shows “your network access was interrupted”, which means that your network went out of track and to continue properly close the database and open again. Error may occur to any operating system irrespective of version such as Windows 8, windows 7, windows Vista, Windows XP, Windows ME and Windows 2000.

Practical scenario:

The Access database just needs to be open and it will usually crash within the next 20-40mins, resulting in the following error message:

Your Network Access Was Interrupted. To Continue Close The Database and then open it again

I am hoping this is a problem with the database itself, as I am not responsible for the server.

Does anyone have a definitive solution?

Error Detail Of Access Error 3043:

Error code: Runtime Error 3043

Error name: Your network access was interrupted

Error description:Your Network Access Was Interrupted. To Continue Close The Database and then open it again

SCREENSHOT OF THE ERROR :

What Are The Symptoms Of Error 3043 ?

This particular Access 3043 Disk or Network Error with Data Access Objects results when you run multiple instances of one visual basic program or you run multiple programs, and all instances or programs does access on the same database.

If the program doesn’t explicitly close all the data access objects then the error will again comes when the second instances of the program tries to work with a data access objects.

Other Symptoms :

  • The active program Window crashes when error 3043 occurs.
  • Sometimes PC also crashes because of the runtime error 3043 while running the program.
  • Displays “your network access was interrupted”.
  • Windows turns incredibly slow and responds slowly to the command of keyboard and mouse.
  • At time PC freezes for few seconds.

The error 3043 displays on the screen during the installation of program, during Windows start-up or shut down, at the time of running of Microsoft Corporation related program, and even during the OS installation. To keep the track of when and where the runtime error 3043 occurs is important for easily troubleshooting them.

What Are The Causes of Access Error 3043 ?

  • Incomplete installation or corrupt download of MS Access Software.
  • Windows registry corruption from a recent MS Access related software change.
  • Corruption of Windows System files or MS Access files due to virus.

Dim db As database
Dim ds As dynaset
Dim sn As snapshot
Dim tb As table
Set db = OpenDatabase(“ ”)
Set ds = db.CreateDynaset(“ ”)
Set sn = db.CreateSnapshot(“ ”)
Set tb = db.OpenTable(“ ”)

Run the following closing statements before the programs ends.

tb.close
ds.close
sn.close
db.close

NOTE:

If you put the .Close methods in the Unload or QueryUnload events, make sure that you have invoked these events before program ends by using the Unload statement (for example, Unload Me). While using the End statement, do it with attention; as it does not invoke the Unload or QueryUnload events.

Deploy an Access application

Access provides a feature-rich platform for developing database applications. A database application is a computer program that provides both a way to store and manage data and a user interface that follows the logic of business tasks (application logic). This article discusses basic deployment planning, packaging and signing, deploying database applications, and the Access Runtime environment.

What do you want to do?

Plan for deployment

Before you begin, you should ask yourself the following questions about the way that the application will be deployed.

Should the data and the logic be separated?

You can create an Access application that combines data management and application logic in one file. This is the default application structure in Access. Combining data management and application logic in one file provides the simplest deployment method, but this method works best only if a few people use the application at the same time, and it involves some risk. For example, a user could cause data loss by unintentionally deleting or damaging the application file. In most cases, you should separate data management and application logic. This helps improve performance and reliability.

One way to separate data and logic is by using the Access Database command (on the Database Tools tab, in the Move Data group). This command splits your database application into two Access files: one for logic (a front-end) and one for data (a back-end). For example, a database called MySolution.accdb is split into two files called MySolution_fe.accdb and MySolution_be.accdb. You put the back-end database in a shared location, such as a network folder. You distribute the front-end file, one copy for each user, to their computers. You can even distribute different front-end files to different users. For more information, see Split an Access database.

Another way to separate data management and application logic is by using a database server program (such as Microsoft SQL Server) for data management, and Access for application logic. For more information, see Migrate an Access database to SQL Server.

Additional reasons for separating data and logic include the following:

Читать еще:  Invalid access token

Data integrity and security If you combine data and logic in one file, the data is exposed to the same risks as the application logic. An Access application that uses separate logic and data files can help protect data integrity and security by leveraging NTFS security features on network folders.

Access users must have read, write, create, and delete permissions to the folder where the front-end file is located. However, you can assign different permissions to the front-end file itself. For example, you may want to assign read-only permissions to some users and read/write permissions to other users.

Your application may require further security options, such as the ability to control which users have access to particular data. In this case, you could use SQL Server or SharePoint to store and manage your application data, and use Access to provide the application logic.

Scalability An Access file can have a maximum size of 2 gigabytes (GB). Although 2GB is a substantial amount of text data, it may be insufficient for some applications, particularly applications that store attachments in database records. If you separate the data and the logic, your application can accommodate more data. If you expect that users will store a large volume of data, you might consider using more than one Access data file.

You should also review the Access program specifications for other scalability information. To learn more about Access specifications, see the article Access specifications.

Network capacity If multiple users will need to use the application at the same time over a network, data corruption is more likely to occur if the data and logic are combined in one file. Moreover, if you combine the data and the logic in one Access file, you cannot optimize the network traffic that Access generates. If multiple users will simultaneously use your application over a network, you should separate the data and the logic, either by using two or more Access files, or by using a database server product for data and Access for application logic.

What will the network environment be like?

Choosing the correct Access database solution for your network environment is a critical step to making it successful. Use the following guidelines to help you make the best choice for your needs.

If you only have a few users to share your Access database with, you can use a single database that each person opens and uses on a home network. For more information, see File sharing over a network in Windows 10.

Local Area Network (LAN)

A LAN is an internal network that usually has excellent performance, but is limited to a small geographical area, such as a single room, building, or group of buildings. When you have more than a few users sharing the database on a LAN, it’s best to split the database, store the back-end database in a network folder, and deploy a copy of the front-end database for each user.

Wide Area Network (WAN)

There are many possible configurations for a WAN, which covers an extensive geographical area. You may have multiple offices across a city connected to a public network, a leased line, or even satellites. Often, a Virtual Private Network (VPN) is used for secure remote access from the home or on the road. A simple way to understand a WAN is that whenever you are outside a LAN but connected to it, you are using a WAN.

Warning Avoid using an Access split database in a WAN because performance can be slow and databases may become corrupt.

There are three supported ways to use Access in a WAN:

An Access database with linked tables to SharePoint lists.

A front-end Access database connection to a backend SQL Server database or Azure SQL.

Remote Desktop Services (RDS) (previously know as Terminal Server), which creates a virtual Windows desktop environment on a users’s client computer. RDS has several advantages:

No installation of Access or an Access database is required as users run the Remote Desktop (RD) client which is available on many devices.

Data transfer is minimized between the client and the server because RD is a thin client that efficiently streams just the user interface.

Users can still copy and paste data and print reports locally from the client computer.

RemoteApp can run just a single program such as a turnkey application for vendors or frontline workers.

For more information, see Welcome to Remote Desktop Services.

Will users have Access?

If all of your users will have Access installed on their computers, they can open and use the application as they would any Access database file.

If some or all of your users will not have Access installed on their computers, you can also deploy the Access Runtime software to those users when you deploy your application. For more information, see Understand and download the Access Runtime.

Deploy an Access application

To deploy an Access application, you need to do the following tasks.

Prepare the database as an application solution

To lock down your solution, control navigation and startup, and set other important options, do the following:

Decide how users navigate the user interface: use a default form, create a switchboard, use a navigation form, or use hyperlinks and command buttons.

Decide if you want to customize the Office ribbon and command menus

Apply a consistent Office theme and background
