Server Service File And Printer Sharing Ports Blocked
- By default, the ports for file sharing are blocked on Windows Server 2012. Specifically, these ports are blocked: UDP 138, File and Printer Sharing (NB-Datagram-In).
- In both Windows 8 and Windows Server 2012 the File and Printer Sharing ports are blocked by default and you will need to open them up for this to work. Solution for Windows 8 You need to open the ports required for File & Print Sharing.
- Windows Server Troubleshooting: 'The RPC server is unavailable'. File and Printer Sharing is not enabled. Domain while the RPC service is blocked.

Jun 02, 2016 With Windows Server 2008 firewall turned off, file sharing works fine. If I turn it on. Networked devices can't find the server via EXPLORER. Windows 2008 firewall blocking file sharing - Windows Server - Spiceworks. Apr 17, 2018 Internet firewalls can prevent browsing and file sharing. Content provided by Microsoft. The following ports are associated with file sharing and server message block (SMB) communications: Microsoft file sharing SMB: User Datagram Protocol (UDP) ports from 135 through 139 and Transmission Control Protocol (TCP) ports from 135.
Client computers in System Center Configuration Manager that run Windows Firewall often require you to configure exceptions to allow communication with their site. The exceptions that you must configure depend on the management features that you use with the Configuration Manager client.
Use the following sections to identify these management features and for more information about how to configure Windows Firewall for these exceptions.
Modifying the Ports and Programs Permitted by Windows Firewall
Use the following procedure to modify the ports and programs on Windows Firewall for the Configuration Manager client.
To modify the ports and programs permitted by Windows Firewall
On the computer that runs Windows Firewall, open Control Panel.
Right-click Windows Firewall, and then click Open.
Configure any required exceptions and any custom programs and ports that you require.
Programs and Ports that Configuration Manager Requires
The following Configuration Manager features require exceptions on the Windows Firewall:
Queries
If you run the Configuration Manager console on a computer that runs Windows Firewall, queries fail the first time that they are run and the operating system displays a dialog box asking if you want to unblock statview.exe. If you unblock statview.exe, future queries will run without errors. You can also manually add Statview.exe to the list of programs and services on the Exceptions tab of the Windows Firewall before you run a query.
Client Push Installation
Enable File And Printer Sharing
To use client push to install the Configuration Manager client, add the following as exceptions to the Windows Firewall:
Outbound and inbound: File and Printer Sharing
But I think the Tenor clef could be added, since on the clef page it is listed, along with the treble, bass and alto clefs, as the fourth clef used in modern notation. (Other clefs are labeled 'obsolete'.) -- 19:37, 16 January 2007 (UTC) I agree.
Tenor clef should probably be added.
Inbound: Windows Management Instrumentation (WMI)
Client Installation by Using Group Policy
To use Group Policy to install the Configuration Manager client, add File and Printer Sharing as an exception to the Windows Firewall.
Client Requests
For client computers to communicate with Configuration Manager site systems, add the following as exceptions to the Windows Firewall:
Outbound: TCP Port 80 (for HTTP communication)
Outbound: TCP Port 443 (for HTTPS communication)
Important
These are default port numbers that can be changed in Configuration Manager. For more information, see How to How to configure client communication ports in System Center Configuration Manager. If these ports have been changed from the default values, you must also configure matching exceptions on the Windows Firewall.
Client Notification
For the management point to notify client computers about an action that it must take when an administrative user selects a client action in the Configuration Manager console, such as download computer policy or initiate a malware scan, add the following as an exception to the Windows Firewall:
I bit the bullet and tried the Windows 10 upgrade (from Windows 7) on my older laptop. Everything seems to work except the headphone jack. Windows 10 driver for Conexant HD Smart Audio; Having trouble signing in? By the way, I doubt if HP has the Windows 10 drivers for your laptop. High definition audio driver windows 7. [Solved] Conexant HD Audio Drivers for Windows 10 By Camilla Mo – Last Updated: 1 year ago Driver Install Drivers, Sound Cards, Windows 10 35 Comments If you want to update Conexant High Definition Audio driver in Windows. HP has provided software updates for Conexant HD Audio Driver. Impacted HP products are shown in the table below. We will update. This package supports the following driver models:Conexant High Definition Audio. Free HP Windows NT/2000/XP/2003/2003 AMD 64-bit/XP AMD 64-bit Version 4. Windows XP 32-bit; Windows XP SP.
Outbound: TCP Port 10123
If this communication does not succeed, Configuration Manager automatically falls back to using the existing client-to-management point communication port of HTTP, or HTTPS:
Outbound: TCP Port 80 (for HTTP communication)
Outbound: TCP Port 443 (for HTTPS communication)
Important
These are default port numbers that can be changed in Configuration Manager. For more information, see How to configure client communication ports in System Center Configuration Manager. If these ports have been changed from the default values, you must also configure matching exceptions on the Windows Firewall.
Remote Control
To use Configuration Manager remote control, allow the following port:
- Inbound: TCP Port 2701
Remote Assistance and Remote Desktop
To initiate Remote Assistance from the Configuration Manager console, add the custom program Helpsvc.exe and the inbound custom port TCP 135 to the list of permitted programs and services in Windows Firewall on the client computer. You must also permit Remote Assistance and Remote Desktop. If you initiate Remote Assistance from the client computer, Windows Firewall automatically configures and permits Remote Assistance and Remote Desktop.
Wake-Up Proxy
If you enable the wake-up proxy client setting, a new service named ConfigMgr Wake-up Proxy uses a peer-to-peer protocol to check whether other computers are awake on the subnet and to wake them up if necessary. This communication uses the following ports:
Outbound: UDP Port 25536
Outbound: UDP Port 9
These are the default port numbers that can be changed in Configuration Manager by using the Power Management clients settings of Wake-up proxy port number (UDP) and Wake On LAN port number (UDP). If you specify the Power Management: Windows Firewall exception for wake-up proxy client setting, these ports are automatically configured in Windows Firewall for clients. However, if clients run a different firewall, you must manually configure the exceptions for these port numbers.
In addition to these ports, wake-up proxy also uses Internet Control Message Protocol (ICMP) echo request messages from one client computer to another client computer. This communication is used to confirm whether the other client computer is awake on the network. ICMP is sometimes referred to as TCP/IP ping commands.
For more information about wake-up proxy, see Plan how to wake up clients in System Center Configuration Manager.
Windows Event Viewer, Windows Performance Monitor, and Windows Diagnostics
To access Windows Event Viewer, Windows Performance Monitor, and Windows Diagnostics from the Configuration Manager console, enable File and Printer Sharing as an exception on the Windows Firewall.
Ports Used During Configuration Manager Client Deployment
The following tables list the ports that are used during the client installation process.
Important
If there is a firewall between the site system servers and the client computer, confirm whether the firewall permits traffic for the ports that are required for the client installation method that you choose. For example, firewalls often prevent client push installation from succeeding because they block Server Message Block (SMB) and Remote Procedure Calls (RPC). In this scenario, use a different client installation method, such as manual installation (running CCMSetup.exe) or Group Policy-based client installation. These alternative client installation methods do not require SMB or RPC.
For information about how to configure Windows Firewall on the client computer, see Modifying the Ports and Programs Permitted by Windows Firewall.
Ports that are used for all installation methods
| Description | UDP | TCP |
|---|---|---|
| Hypertext Transfer Protocol (HTTP) from the client computer to a fallback status point, when a fallback status point is assigned to the client. | -- | 80 (See note 1, Alternate Port Available) |
Ports that are used with client push installation
In addition to the ports listed in the following table, client push installation also uses Internet Control Message Protocol (ICMP) echo request messages from the site server to the client computer to confirm whether the client computer is available on the network. ICMP is sometimes referred to as TCP/IP ping commands. ICMP does not have a UDP or TCP protocol number, and so it is not listed in the following table. However, any intervening network devices, such as firewalls, must permit ICMP traffic for client push installation to succeed.
| Description | UDP | TCP |
|---|---|---|
| Server Message Block (SMB) between the site server and client computer. | -- | 445 |
| RPC endpoint mapper between the site server and the client computer. | 135 | 135 |
| RPC dynamic ports between the site server and the client computer. | -- | DYNAMIC |
| Hypertext Transfer Protocol (HTTP) from the client computer to a management point when the connection is over HTTP. | -- | 80 (See note 1, Alternate Port Available) |
| Secure Hypertext Transfer Protocol (HTTPS) from the client computer to a management point when the connection is over HTTPS. | -- | 443 (See note 1, Alternate Port Available) |
Ports that are used with software update point-based installation
| Description | UDP | TCP |
|---|---|---|
| Hypertext Transfer Protocol (HTTP) from the client computer to the software update point. | -- | 80 or 8530 (See note 2, Windows Server Update Services) |
| Secure Hypertext Transfer Protocol (HTTPS) from the client computer to the software update point. | -- | 443 or 8531 (See note 2, Windows Server Update Services) |
| Server Message Block (SMB) between the source server and the client computer when you specify the CCMSetup command-line property /source:<Path>. | -- | 445 |
Ports that are used with Group Policy-based installation
| Description | UDP | TCP |
|---|---|---|
| Hypertext Transfer Protocol (HTTP) from the client computer to a management point when the connection is over HTTP. | -- | 80 (See note 1, Alternate Port Available) |
| Secure Hypertext Transfer Protocol (HTTPS) from the client computer to a management point when the connection is over HTTPS. | -- | 443 (See note 1, Alternate Port Available) |
| Server Message Block (SMB) between the source server and the client computer when you specify the CCMSetup command-line property /source:<Path>. | -- | 445 |
Ports that are used with manual installation and logon script-based installation
| Description | UDP | TCP |
|---|---|---|
| Server Message Block (SMB) between the client computer and a network share from which you run CCMSetup.exe. When you install Configuration Manager, the client installation source files are copied and automatically shared from the <InstallationPath>Client folder on management points. However, you can copy these files and create a new share on any computer on the network. Alternatively, you can eliminate this network traffic by running CCMSetup.exe locally, for example, by using removable media. | -- | 445 |
| Hypertext Transfer Protocol (HTTP) from the client computer to a management point when the connection is over HTTP, and you do not specify the CCMSetup command-line property /source:<Path>. | -- | 80 (See note 1, Alternate Port Available) |
| Secure Hypertext Transfer Protocol (HTTPS) from the client computer to a management point when the connection is over HTTPS, and you do not specify the CCMSetup command-line property /source:<Path>. | -- | 443 (See note 1, Alternate Port Available) |
| Server Message Block (SMB) between the source server and the client computer when you specify the CCMSetup command-line property /source:<Path>. | -- | 445 |
Ports that are used with software distribution-based installation
| Description | UDP | TCP |
|---|---|---|
| Server Message Block (SMB) between the distribution point and the client computer. | -- | 445 |
| Hypertext Transfer Protocol (HTTP) from the client to a distribution point when the connection is over HTTP. | -- | 80 (See note 1, Alternate Port Available) |
| Secure Hypertext Transfer Protocol (HTTPS) from the client to a distribution point when the connection is over HTTPS. | -- | 443 (See note 1, Alternate Port Available) |
Notes
1 Alternate Port Available In Configuration Manager, you can define an alternate port for this value. If a custom port has been defined, substitute that custom port when you define the IP filter information for IPsec policies or for configuring firewalls.
2 Windows Server Update Services You can install Windows Server Update Service (WSUS) either on the default Web site (port 80) or a custom Web site (port 8530).
File And Printer Sharing Windows Xp
After installation, you can change the port. You do not have to use the same port number throughout the site hierarchy.
Server Service File And Printer Sharing Ports Blocked By Comcast
If the HTTP port is 80, the HTTPS port must be 443.
Print Sharing Port
If the HTTP port is anything else, the HTTPS port must be 1 higher. For example, 8530 and 8531.
