3.2.3 Improving WinRM Enumeration Performance
When an enumeration command is executed, the default WinRM configuration gets only 20 instances at
a time and therefore slows down the system drastically. Changing the WinRM configuration to allow a
greater number, such as 50, will reduce the time taken by the enumeration operations.
Execute the following command to get instances in groups of up to 50.
winrm set winrm/config @{MaxBatchItems="50"}
Additionally, increasing the allotted maximum envelope size and timeout can also increase
performance.
winrm set winrm/config @{MaxEnvelopeSizekb="150"}
winrm set winrm/config @{MaxTimeoutms ="60000"}
Other optional WinRM configuration commands are listed below for convenience. To get the current
WinRM configuration settings, execute the following command.
winrm g winrm/config
By default, the client computer requires encrypted network traffic. To allow the client computer to
request unencrypted traffic, execute the following command:
winrm s winrm/config/Client @{AllowUnencrypted="true"}
TrustedHosts is an array that specifies the list of remote computers that are trusted. Other computers
in a workgroup or computers in a different domain should be added to this list.
Note: The computers in the TrustedHosts list are not authenticated.
Execute the following command to allow all computers to be included in TrustedHosts.
winrm s winrm/config/Client @{TrustedHosts="*"}
Basic authentication is a scheme in which the user name and password are sent in clear text to the
server or proxy. This method is the least secure method of authentication. The default is True.
Execute the following command to set client computer to use Basic authentication.
winrm s winrm/config/Client/Auth @{Basic="true"}
3.2.4 Specifying StartTime, Until Time, and TIME_NOW Parameters
The several methods that attach a virtual USB device to the target system accept a StartTime and Until
parameter. The parameter data type is CIM date-time. If the StartTime parameter is null the action
will not be started. If the Until parameter is null, the default value will be 17 hours. The date-time
data type is defined in the CIM Infrastructure Specification
