License does not work when computer is disconnected from the Network

Windows 2000/XP Media Sensing Feature
If the computer is disconnected from the network (no "link") and the "Media Sensing" is enabled, the TCP/IP system will be shut down. Unfortunately, FLEXlm (the licensing software that Fluent Inc uses, relies on TCP/IP for its communication, therefore, the license will not check out.

To prevent your network adapter from detecting the link state:

Manually make the following changes to the Windows Registry.

1.Click on the Start button, Run
2.Type: Regedt32
3.Browse to: HKEY_LOCAL_MACHINESystemCurrentControlSetServicesTcpipParameters
4.Add the following registry value:
Value Name: DisableDHCPMediaSense
Data Type: REG_DWORD -Boolean
Value Data Range: 0, 1 (False, True) Default: 0 (False)

Description: This parameter controls DHCP Media Sense behavior. If you set this value data to 1, DHCP, and even non-DHCP, clients ignore Media Sense events from the interface. By default, Media Sense events trigger the DHCP client to take an action, such as attempting to obtain a lease (when a connect event occurs), or invalidating the interface and routes (when a disconnect event occurs).

5.Restart your computer after you have made the necessary changes.
Note: You must have Administrative privileges in order to change the Windows Registry.

Note: There are some side effects of disabling the "Media Sensing" feature. For additional information see <a target=_blank href=""></a>
