This method deletes a property from a configuration service provider node.
HRESULT DeleteProperty([in] REFGUID guidProperty);
A value of S_OK indicates that a node was successfully found. CFGMGR_E_PROPERTYNOTSUPPORTED indicates that this node does not manage or implement the property itself, but delegates it to ConfigManager2. E_NOTIMPL indicates this method is not supported by this node.
For externally–transactioned nodes, if this method is implemented, then ICSPNode::SetProperty must also be implemented or rollback will fail.
