Active System Manager Release 8.1.1 Installation Guide

ASM manages resource on Microsoft System Center Virtual Machine Manager through Windows Remote Management (WinRM). Windows RM must be enabled on the SCVMM server as well as on Active Directory and DNS servers used in SCVMM/HyperV deployments. ASM deployments support Active Directory and DNS servers which exist on the same machine. If Active Directory and DNS servers exist on separate machines, some manual tear-down may be required to remove host entries from the DNS server. ASM requires Windows RM to utilize default port and basic authentication. To enable these settings, on the SCVMM server and on the Active Directory and DNS server used in HyperV deployments, open a Windows PowerShell interface with administrator permissions and run the following commands:

winrm set winrm/config/client/auth '@{Basic="true"}'
                                 winrm set winrm/config/service/auth '@{Basic="true"}'
                                 winrm set winrm/config/service '@{AllowUnencrypted="true"}'
                                 
                              

The default amount of memory allocated for WinRM processes is limited to 150 MB. To avoid out of memory errors, increase the memory size to 1024:

winrm set winrm/config/winrs '@{MaxMemoryPerShellMB="1024"}'

For Windows 2008:

winrm quickconfig
