PORTS TO BE OPEN FOR SCCM 2012

Configuring firewall exceptions is yet another important thing. We will look at opening SQL ports for SCCM. There are few services that needs to be allowed through windows firewall to ensure client installation works fine.
can i make all this firewall rules in sccm2012 server only or must be put in group policy ? why?and if group policy what ou does the sccm 2012 server hosted and the client machine also what ou they will be hosted and if this group policy applied also in ou hosted client machinethank you
I would recommend to open the ports using group policy for entire domain. SQL replication ports TCP 1433 and 4022 must be opened because these are required to access SQL and for SQL to replicate to other SQL servers. WMI and File and Print sharing services must be enabled. Both the steps are shown in the post.
This is a little tool I created for testing the required TCP ports on SCCM client systems. It will check that the required inbound ports are open and that the client can communicate to its management point, distribution point and software update point on the required ports. It also includes a custom port checker for testing any inbound or outbound port.
By default, Microsoft Windows enables the Windows Firewall, which closes port 1433 to prevent Internet computers from connecting to a default instance of SQL Server on your computer. Connections to the default instance using TCP/IP are not possible unless you reopen port 1433. We will now create a group policy to open TCP ports 1433 and 4022.
3. At this point, the WinRM listeners are listening on the correct ports, the Windows Firewall is probably rejecting any remote connections to those ports. You need to open those ports. To do so, run the following command. The New-NetFirewallRule below is creating a Windows Firewall rule to allow all inbound TCP connections to a custom port.
WinRM uses ports 5985 (HTTP) and 5986 (HTTPS). To open the firewall for port 5985, expand Computer Configuration > Policies > Windows Settings > Security Settings > Windows Firewall with Advanced Security > Windows Firewall with Advanced Security > Inbound Rules. Right-click the Inbound Rules node and choose New Rule.
If your organization does not allow those ports and protocols open to all addresses, you can restrict access to only the following domains so that WSUS and Automatic Updates can communicate with Microsoft Update:
The steps for configuring the firewall above are meant for a corporate firewall positioned between WSUS and the Internet. Because WSUS initiates all its network traffic, there is no need to configure Windows Firewall on the WSUS server. Although the connection between Microsoft Update and WSUS requires ports 80 and 443 to be open, you can configure multiple WSUS servers to synchronize with a custom port.
Note: TCP Port 80 is open for outgoing communications by default in most firewall software. So you should not have to open any ports in the firewall software running on Rhino workstations.
Notes:Port numbers in computer networking represent communication endpoints. Ports are unsigned 16-bit integers (0-65535) that identify a specific process, or network service. IANA is responsible for internet protocol resources, including the registration of commonly used port numbers for well-known internet services.Well Known Ports: 0 through 1023.Registered Ports: 1024 through 49151.Dynamic/Private : 49152 through 65535.TCP ports use the Transmission Control Protocol, the most commonly used protocol on the Internet and any TCP/IP network. TCP enables two hosts to establish a connection and exchange streams of data. TCP guarantees delivery of data and that packets will be delivered in the same order in which they were sent. Guaranteed communication/delivery is the key difference between TCP and UDP.UDP ports use the Datagram Protocol. Like TCP, UDP is used in combination with IP (the Internet Protocol) and facilitates the transmission of datagrams from one computer to applications on another computer, but unlike TCP, UDP is connectionless and does not guarantee reliable communication; it's up to the application that received the message to process any errors and verify correct delivery. UDP is often used with time-sensitive applications, such as audio/video streaming and realtime gaming, where dropping some packets is preferable to waiting for delayed data.When troubleshooting unknown open ports, it is useful to find exactly what services/processes are listening to them. This can be accomplished in both Windows command prompt and Linux variants using the "netstat -aon" command. We also recommend runnig multiple anti-virus/anti-malware scans to rule out the possibility of active malicious software. For more detailed and personalized help please use our forums.
The ports used by Parallels Mac Management should NOT be used by other programs. Please review the following table and make sure that the ports listed are available. Please note that the table doesn't include the ports used by the standard System Center Configuration Manager 2012 services, and by the standard Windows services.
In our organization, System Center Configuration Manager is used to distribute software, but now we have decided to use the functions of this system to implement the functions of remote management of client PCs (which is very much required by Helpdesk). However, it is worth considering that in order for the remote control function to work (the utility is called SCCM Remote Tools), you need to open a number of ports on both network equipment and Windows Firewall. 2b1af7f3a8
