Users cannot launch Network Connect; instead they receive nc.windows.app.23704 or nc.windows.app.23712 errors.
Problem or Goal:
This issue can occur when Network Connect cannot configure the Adapter.
There are three common possible causes for these errors:
Media Sense is disabled
The easiest way to check if Media Sense has been disabled is to open up a command prompt and run "ipconfig /all" when Network Connect is not connected. If you see the Media State parameter then Media Sense should still be enabled.
You can re-enable it by going to \HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Tcpip\Parameters and change DisableDHCPMediaSense (dword) key from 1 to 0. By default Media Sense is enabled on all XP machines and so if you do not find DisableDHCPMediaSense, then you can usually assume that Media Sense is turned on.
DHCP Client Service is disabled
You can re-enable it by going to Control Panel > Administrative Tools > Services
A client firewall/antivirus is blocking Network Connect
