Opening ports in Windows Firewall

The following instructions are for opening ports in Windows Firewall. If you have a non-Microsoft firewall installed, consult the guide for that firewall about how to open ports. Opening ports in Windows Firewall can be done through the command line.

Important

Opening ports in your firewall can leave your server exposed to malicious attacks. Make sure that you understand firewall systems before you open ports.

To open Windows Firewall ports by using the command line (do one of the following):

Open a Command Prompt window with elevated user rights, type the following, and then press Enter.

On computers that are running Windows Server 2003, type:

netsh firewall add allowedprogram program=%windir%\System32\WindowsPowerShell\v1.0\powershell.exe name="ServerMigration" mode=ENABLE

On computers that are running Windows Server 2012 R2, Windows Server 2012, Windows Server 2008 R2, or Windows Server 2008, type the following commands in order, and press Enter after each command.

netsh advfirewall firewall add rule name=ServerMigration(TCP-In) dir=in program=%windir%\System32\WindowsPowerShell\v1.0\powershell.exe action=allow protocol=TCP localport=7000

netsh advfirewall firewall add rule name=ServerMigration(UDP-In) dir=in program=%windir%\System32\WindowsPowerShell\v1.0\powershell.exe action=allow protocol=UDP localport=7000

If you have changed the default behavior of Windows Firewall to block all outbound traffic on computers that are running Windows Server 2012 R2, Windows Server 2012, Windows Server 2008 R2, or Windows Server 2008, you must explicitly allow outbound traffic on UDP port 7000. To do this, open a Command Prompt window with elevated user rights, type the following, and then press Enter.
```
netsh advfirewall firewall add rule name=ServerMigration(UDP-Out) dir=out program=%windir%\System32\WindowsPowerShell\v1.0\powershell.exe action=allow protocol=UDP localport=7000
```

Closing ports in Windows Firewall

As a best practice, we recommend that you close Windows Firewall ports after the data transfer operation is completed.

To close Windows Firewall ports by using the command line

Do one of the following:
- On computers that are running Windows Server 2003, open a Command Prompt window, type the following, and then press Enter.
```
netsh firewall delete allowedprogram program=%windir%\System32\WindowsPowerShell\v1.0\powershell.exe
```
- On computers that are running Windows Server 2012 R2, Windows Server 2012, Windows Server 2008 R2, or Windows Server 2008, open a Command Prompt window with elevated user rights, type the following two commands, and press Enter after each command.
```
netsh advfirewall firewall delete rule name=ServerMigration(TCP-In)

netsh advfirewall firewall delete rule name=ServerMigration(UDP-Out)
```

Detect reparse points and hard links

The following commands can be used to detect reparse points and mounted volumes in any folder and its subfolders. Open a Command Prompt window, type the following commands to detect reparse points, in which D:\Test represents the hard disk drive and folder that you want to search, and then press Enter.

dir D:\Test\* /S /A:L

The option /A:L specifies that only reparse points need to be enumerated. The output is similar to the following:

Volume in drive D has no label.
Volume Serial Number is 3AE4-E412

Directory of D:\Test\Links

10/07/2008  03:44 PM    <JUNCTION>     JunctionMSIT [d:\test\targets\msit]
10/07/2008  03:42 PM    <SYMLINK>      LinkMSIT [d:\test\targets\msit]
10/07/2008  03:41 PM    <SYMLINKD>     SymLinkMSIT [d:\test\targets\msit]

Directory of D:\Test\Targets

10/07/2008  05:35 PM    <JUNCTION>     Volume [\??\Volume{0674413f-760d-11dd-beb3-806e6f6e6963}\]
0 File(s)              0 bytes

Total Files Listed:
1 File(s)              0 bytes
3 Dir(s)  17,918,840,832 bytes free

To enumerate hard links on a file on Windows Server 2012 R2, Windows Server 2012, or Windows Server 2008 R2, open a Command Prompt window with elevated user rights, type the following command, and then press Enter.

fsutil hardlink list D:\Test\File.txt

To enumerate hard links on all files in a folder on Windows Server 2012 R2, Windows Server 2012, or Windows Server 2008 R2, run the following command in a Windows PowerShell session that has been opened with elevated user rights:

Get-ChildItem D:\* | %{'Links for: ' + $_.FullName; fsutil hardlink list $_.FullName; ""}

For more information about enumerating hard links on computers that are running Windows Server 2008 or Windows Server 2003, see FindFirstFileNameW function on MSDN.

Migrated and nonmigrated attributes for local users and groups

For more information about the attributes of local users and groups that can be migrated, see the Local User and Group Migration Guide.
