Network Settings tab

  • Article

Applies To: Windows Server 2008

On this tab, you can set the Multicast IP Address, UDP Port Range, and Network Profile. After you configure Windows Deployment Services server, if you modify any of these options, or the RPC port number (by running wdsutil /set-server /rpcport:<portnum>), you must restart the service before the changes will take effect. If you do not restart the service, the server will use the old values and may not answer clients. To restart the service, do one of the following:

  • Right-click Windows Deployment Services in the MMC snap-in and click Restart

  • Run net stop wdsserver and then run net start wdsserver from the command line

Setting Details

Multicast IP Address

This setting is applicable only if you are enabling multicast transmissions. You can choose from the following options:

  • Obtain IP address from DHCP. You can select this option only if your DHCP server supports it. If you select it, the IP address will be obtained by using the Multicast Address Dynamic Client Allocation Protocol (RFC 2730, Multicast) for each namespace. For more information, see https://go.microsoft.com/fwlink/?LinkId=81507. You might want to select this setting for manageability reasons—for example, if you have multiple Windows Deployment Services servers for the same clients.

    Selecting this setting is the same as running:

    WDSUTIL /Set-Server [/Server:<name>] /Transport /ObtainIPFrom:DHCP

  • Use IP address from the following range. This option specifies the range of IP addresses for the Windows Deployment Services server to use. Setting this option is the same as running:

    WDSUTIL /Set-Server [/Server:<name>] /Transport /ObtainIPv4From:Range /Start:x.x.x.x /End:y.y.y.y

    Note
    Be sure to specify static ranges that do not overlap to ensure that each server is using a unique IP address.

UDP Port Range

We recommend that you do not modify this range.

This setting specifies the range of UDP ports to use. These ports will be used by the Windows Deployment Services server for multicasting and other components such as the TFTP provider.

Before you change this range, you need to have at least as many ports as you have sessions and concurrent clients accessing the server. In terms of multicasting, a session is a network interface on your server. To calculate the number of sessions, multiply the number of network adapters on your server by the number of images that could be concurrently multicasted. For example, if you have two network adapters, and clients are connected on both interfaces, the content will be sent on the network twice (once from each interface). So in this case, you would need at least two ports.

Because this range is also used by the TFTP provider, you will need as many available ports as you have concurrent clients accessing the server.

This setting is the same as running:

WDSUTIL /Set-Server [/Server:<name>] /Transport /StartPort:x /EndPort:y

Network Profile

Specifies the network speed of your organization. Each profile contains settings to optimize performance for the specified speed (such as the maximum transport window size, the transport cache size, and the block size). You can view the profiles at HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WDSServer\Providers\Multicast\Profiles

Select Custom if you want to customize the settings yourself by editing the registry. You should not modify the other profiles that are provided. You should create a custom profile even if you only want to change one setting. Selecting this option is the same as running:

WDSUTIL /Set-Server [/Server:<name>] /Transport /Profile:{10Mbps|100Mbps|1Gbps|Custom}
