Pro/E license borrowing ethernet failure

[Lohbauer]

Morning All,

I have a user running WF 4.0 on a Win 7 laptop. We have a borrow enabled license pack. After the license is borrowed and the laptop is offline; Proe is started thenthe system fails the attempt stating it can't find an ethernet adapter. We have multiple users borrowing licenses frequently and this is a new one for me. Not being deeply hardware savvy I'm looking here first then I'll ask IT to check the laptop.

Has anyone had this ethernet adaptererror after borrowing a license?

TIA

Title
When Not Connected to a Network, Windows Machines May Return "HostID" Errors ( -96, -15, -9) for Pro/ ENGINEER and the FLEXnet License Server Due to the Windows Media Sensing Feature.

Description
When disconnected from a network Windows machines may disable certain network cards resulting in licensing errors from Pro/ENGINEER and the PTC License Server.

Pro/ENGINEER may return
error: "(-96) License server host is down or not responding" or error: "(-15) Cannot connect to license server system" if configured to a license server
or
error: "License request failed for feature PROE_Foundation: -9: Invalid host." if configured to a locked license.

FLEXnet License Server error log may contain messages similar to the following:

Error: Wrong hostid on SERVER line for license file: <flexnet loadpoint=">\licensing\license.dat
SERVER line says PTC_HOSTID=00-11-22-AA-BB-CC, hostid is PTC_HOSTID=00-AA-11-BB-22-CC

Resolution
This issue is related to the 'media sensing' feature of Windows 2000 and later (including XP and Vista) and disabling this 'media sensing' feature will resolve the issue.
