If you want to enable basic authentication for the user who is connecting to the proxy server, select the Allow basic authentication password is sent in cleartext checkbox.
On the Connect to Upstream Server page, select start Connecting. On the Choose Languages page, you have the option to select the languages from which WSUS will receive updates: all languages or a subset of languages.
Selecting a subset of languages will save disk space, but it's important to choose all the languages that all the clients of this WSUS server need. If you choose to get updates only for specific languages, select Download updates only in these languages , and then select the languages for which you want updates. Otherwise, leave the default selection. If you select the option Download updates only in these languages , and this server has a downstream WSUS server connected to it, this option will force the downstream server to also use only the selected languages.
The Choose Products page allows you to specify the products for which you want updates. Select product categories, such as Windows, or specific products, such as Windows Server Selecting a product category selects all the products in that category.
On the Choose Classifications page, select the update classifications that you want to get. Choose all the classifications or a subset of them, and then select Next. The Set Sync Schedule page enables you to select whether to perform synchronization manually or automatically. Set the time for First synchronization , and then specify the number of synchronizations per day that you want this server to perform. On the Finished page, you have the option to start the synchronization now by selecting the Begin initial synchronization checkbox.
Select Next if you want to read more about additional settings, or select Finish to conclude this wizard and finish the initial WSUS setup. You'll use this console to manage your WSUS network, as described later on. This will allow the attacker to install malicious software on client computers. This effort involves creating an SSL certificate for the server. The steps that are required to get an SSL certificate for the server are beyond the scope of this article and will depend on your network configuration.
For more information and for instructions about how to install certificates and set up this environment, we suggest the following articles:. Suite B PKI step-by-step guide. Implementing and administering certificate templates.
Active Directory Certificate Services upgrade and migration guide. Configure certificate autoenrollment. By default, this is port A second port uses HTTP to send update payloads.
WSUS is designed to encrypt update metadata only. This is the same way that Windows Update distributes updates. To guard against an attacker tampering with the update payloads, all update payloads are signed through a specific set of trusted signing certificates.
In addition, a cryptographic hash is computed for each update payload. The hash is sent to the client computer over the secure HTTPS metadata connection, along with the other metadata for the update.
When an update is downloaded, the client software verifies the payload's digital signature and hash. If the update has been changed, it's not installed. You must use the certificate store for the local computer.
You can't use a user's certificate store. If you change these ports, you must use two adjacent port numbers. This creates a potential attack vector.
To help protect this connection, consider the following recommendations:. Deploy Internet Protocol security IPsec to help secure network traffic. Local publishing allows you to create and distribute updates that you design yourself, with your own payloads and behaviors. Enabling and configuring local publishing is beyond the scope of this article. For full details, see Local publishing. Local publishing is a complicated process and is often not needed.
Before you decide to enable local publishing, you should carefully review the documentation and consider whether and how you'll use this functionality. Computer groups are an important part of using WSUS effectively. Computer groups permit you to test and target updates to specific computers. There are two default computer groups: All Computers and Unassigned Computers. By default, when each client computer first contacts the WSUS server, the server adds that client computer to both of these groups.
You can create as many custom computer groups as you need to manage updates in your organization. As a best practice, create at least one computer group to test updates before you deploy them to other computers in your organization. There are two approaches to assigning client computers to computer groups.
The right approach for your organization will depend on how you typically manage your client computers. Server-side targeting : This is the default approach. This approach gives you the flexibility to quickly move client computers from one group to another as circumstances change. But it means that new client computers must manually be moved from the Unassigned Computers group to the appropriate computer group. Client-side targeting : In this approach, you assign each client computer to computer groups by using policy settings set on the client computer itself.
This approach makes it easier to assign new client computers to the appropriate groups. You do so as part of configuring the client computer to receive updates from the WSUS server.
But it means that client computers can't be assigned to computer groups, or moved from one computer group to another, through the WSUS Administration Console. Instead, the client computers' policies must be modified. You must create computer groups by using the WSUS Administration Console, whether you use server-side targeting or client-side targeting to add client computers to the computer groups. In the Add Computer Group dialog, for Name , specify the name of the new group.
The following sections detail the ports that are used for communication in Configuration Manager. The arrows in the section title show the direction of the communication:.
Wake-up proxy also uses ICMP echo request messages from one client to another client. Clients use this communication to confirm whether the other client is awake on the network. ICMP is sometimes referred to as ping commands. However, any host-based firewalls on these client computers or intervening network devices within the subnet must permit ICMP traffic for wake-up proxy communication to succeed.
For more information, see Ports and data flow. For more information, see CMG data flow. Use client settings to configure the alternate port for express updates. For more information, see Port that clients use to receive requests for delta content. If you enable a host-based firewall, make sure that the rules allow the server to send and receive on these ports. It doesn't configure the outbound send rules. A Configuration Manager client doesn't contact a global catalog server when it's a workgroup computer or when it's configured for internet-only communication.
Configuration Manager uses these connections to build the CMG channel. The specific port required depends upon the management point configuration. For more information, see What is the administration service?
For more information, see External notifications. This communication is used when you deploy certificate profiles by using the certificate registration point. The communication isn't used for every site server in the hierarchy. Instead, it's used only for the site server at the top of the hierarchy. You can move the content library to another storage location to free up hard drive space on your central administration or primary site servers.
For more information, see Configure a remote content library for the site server. During the installation of a site that uses a remote SQL Server to host the site database, open the following ports between the site server and the SQL Server:.
You can define an alternate port in Configuration Manager for this value. If you define a custom port, use that custom port in the IP filter information for IPsec policies or to configure firewalls. After installation, you can change the port. You don't have to use the same port number throughout the site hierarchy. Configuration Manager doesn't support dynamic ports. By default, SQL Server named instances use dynamic ports for connections to the database engine.
When you use a named instance, manually configure the static port. TFTP is designed to support diskless boot environments. These ports are defined by Microsoft between and For more information, see Service overview and network port requirements for Windows. However, during the actual PXE boot, the network card on the device selects the dynamically allocated high port it uses during the TFTP transfer.

This means if your first rule blocks all outgoing traffic to 0. Add a comment. Active Oldest Votes. I've found solution. I wonder why my default settings didn't already have this?
Anyway it worked! Improve this answer. When adding this rule on Windows 8, Windows Firewall warns me that this rule would not work as expected. Do you know what could it mean? Windows Update is calling a remote service. So the rule must be outbound , not inbound. It works like a charm, even on Windows 7 — Marco Demaio.
Is it important to specify the svchost. I'm afraid not specifying it would allow any app to make a remote call. When I specify it, there is a strange message: "Windows Services have been restricted with rules that allow expected behavior only. If it really is just the Firewall, this should allow you to use Windows Update. KCotreau KCotreau I have tried to restore to default, however, the same problem still exists.
Is this then not a firewall issue? I don't understand how than stopping the firewall will cause it to work. Open Command Prompt as administrator and type the following commands, one by one press ENTER after each command : - netsh winhttp reset proxy - net stop wuauserv - net start wuauserv Try to install the updates again.

He already said Windows Update works if he turns off the firewall "it seems to update fine when I don't have the firewall on" , so no need to reset any of this. You're right Here is how to change firewall settings in Windows 7, you can watch the video to learn the steps ; Allow a program to communicate through Windows Firewall By default, most programs are blocked by Windows Firewall to help make your computer more secure.
