Computer configuration > Policies > Security Settings > Local Policies > Security Options:
- DCOM: Machine Access Restrictions In Security Descriptor Definition Language Syntax
- DCOM: Machine Launch Restrictions In Security Descriptor Definition Language Syntax
Below are the corresponding registry settings on the client machine which indicates that the DCOM group policy is applied.
- HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\WindowsNT\DCOM\MachineAccessRestriction
- HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\WindowsNT\DCOM\MachineLaunchRestriction
