This is a good criteria for single user installations, because it is still available after a reinstallation of a machine and is independent of disk imaging. There are a few things to be considered in a server environment.
If a server has more than one adapter, with some PCs accessing the server through adapter 1, some through adapter 2, a copy protection violation will occur. In this case we recommend switching to the criteria Volume ID + UNC Pathname.
In a subnet portioned network environment the MAC address should not be used. All PCs in outer subnets cannot retrieve the MAC address. Switch to Volume ID or Hostname in combination with UNC path as means of copy protection.
All-In-One Protector can be used on a Novell server for licensing, but the Software Copy Protection will not work, because the hardware information like Volume ID or MAC address cannot be retrieved from the server.
Some W-Lan Adapters are 'invisble' for Windows, whenever the network cable is unplugged or a notebook is in battery mode. Switch to hostname.
If a PDA with an in-built network adapter is connected to the PC during the activation, it could happen that this network adapter is used, because the network adapter of the PDA is added to the PCs network adapters. The PDA should be disconnected, and then the MAC address can be used for copy protection.
The software copy protection with installation code 2 cannot be used, whenever using Windows 98 / NT with the license file being on the server. A Windows 98 / NT system cannot retrieve this information from the server.
Recommendation: Use installation code 5, 1 or 3 within a network installation with Windows 98 / NT machines.
The installation code 2 works with Windows 98 / NT, whenever the license file is on the local machine.
Note:
•There will be no future support for Windows 98 and All-In-One Protector with the complete functionality.
•A MAC address can be faked with tools
•If All-In-One Protector cannot retrieve a MAC address the instcode 2 is empty
Pros/Cons
+ After reinstallation of Windows, the MAC address does not change
+ If an image tool is used, the MAC address is still different
+ Good within a network, because the MAC address must be unique
- See considerations above for multiple network cards
- Restricted use in network environment with Windows 98 / NT machines
- Allows to install the application multiple times on the same server / computer
Recommendation
Should be used for enterprise users because disk imaging is often used to set up multiple machines and a reinstallation of Windows does not need a new licensing.
