This custom task sequence action is used specifically to install and configure Nomad in WinPE – typically done in order to support the use of pre-staged content.
When run, this task:
  1. Creates the Nomad registry values and sets the parameters passed from the task sequence action.
  2. Disables the firewall in the WinPE environment if set in the task sequence action.
  3. Self-installs Nomad.
  4. Configures registry COM.
  5. Licenses Nomad from parameter passed from the task sequence action.
  6. Enables multicast if set in the task sequence action.
  7. Starts the Nomad service.
This task sequence action:
  • Is specifically for use in WinPE and requires NomadBranch.exe, SMSNomad.exe and SNOttfps.dll to be added to the WinPE image (the NomadBranchTools.msi in Configuration Manager 2012 does this automatically).
  • Must be set as one of the tasks following Restart in Windows PE and before Apply Operating System.
  • Must include the license key parameter

Configurable parameters

ParameterDefault valueDescription
NameInstall and Configure NomadName for the custom task sequence action.
DescriptionAction to Install and configure Nomad in WinPEDescription for the custom task sequence action.
License key Mandatory field.
Workrate80Sets the work rate. This is the proportion of available (free) bandwidth to use.
P2P Port1779Port used to broadcast election messages.
SpecialNetShare8224 (0x2020)Must be an integer. See more SpecialNetShare for more information

Must be an integer. See P2PEnabled for more information.

If upgrading from 6.1 change P2PEnabled to 7 to continue using Connectionless (server and client) and SMB.

CompatibilityFlags0x100002Must be an integer. See CompatibilityFlags for more information.
Multicast support0Enables different levels of multicast support. See MulticastSupport for more information. If the value is not 0, the MADCAP scope and multicast TTL fields are enabled.
MADCAP scope MADCAP scope for multicast. Either a scope name, or of the form <MADCAP_ServerIP>,<MADCAP_Scope_IP>,<TTL> or <MADCAP_ServerIP>, <MADCAP_Scope_IP>. See MultiCastMADCAPScope for more information.
Multicast TTL Optional multicast time to live. See MultiCastMADCAPScope for more information.
Disable firewallEnabled by default.Disables the Windows PE firewall so that NomadPackageLocator and Nomad can communicate with other peers on the local network.
Log file size10485760 (10MB)Sets the maximum size for the Nomad log file.
Enable single site downloadDisabled by default.Enables the SSD feature. For Nomad running in WinPE, sets the SSDEnabled registry value to 0x1 so that SSD is enabled but the machine will be set to just retrieve downloads via SSD and not to put themselves forward to provide content.
WakeUp0 (disabled)Enables WakeUp integration. If not 0, sets the WakeUpEnabled registry value to enable peers to be woken if necessary to supply the content.
ActiveEfficiency URL ""

Sets the location of the ActiveEfficiency Web service, usually of the form http://server/ActiveEfficiency or 
http://server:port/ActiveEfficiency depending on how the ActiveEfficiencyWeb service is configured.

HTTPS is not supported for this property.
Max. machines from ActiveEfficiency 10Specifies the maximum number of devices (i.e. machines) with content (package, application or software update) that Nomad may ask from the ActiveEfficiency server in one call. Separate calls are made for local devices (for WakeUp only) and site devices (for SSD and WakeUp). The maximum value is 20.
WakeUp batch size 10Specifies the maximum number of machines to wake up in one call, for subnet and site separately. (So up to twice this number of requests will be sent in total if wakeup is enabled for both subnet and site.) The next batch will be launched, if necessary, after a re-election (usually a periodic election). The value cannot be greater than the maximum number of machines from ActiveEfficiency and hence itself cannot be more than 20.

Non-Configurable settings

SettingDefault valueDescription
P2PElectionWeight10Helps determine the outcome of Nomad elections. The higher the value the more chances the machine has to win the election.
EncryptionType0Determines the type of encryption used by Nomad to encrypt its license key and communications between Nomad peers.
