CRM has no specific functionality to restrict access to certain machines, but you may be able to achieve this by more general functionality. One option is to block the Crm url on specific client machines, as per the previous post, but that only works for
known machines.
Another option could be to add restrictions in IIS on the Crm Server. This can restrict access to only certain IP addresses, but that would only work if the laptops always connect via a known set of IP addresses - this is probably OK if they're always connected
via a company network, either directly, or via a VPN
