IT Management Suite

As PC Transplant is not able to capture WLAN profiles, how can this goal still be achieved?

The following method can be used on Windows XP Service Pack 2 and Service Pack 3.

Requirements for Service Pack 2:

1. Download and install Wireless LAN API (KB918997)

   Installing this set of application programming interfaces (APIs) will enable you to create applications that can manage wireless LAN profiles and connectivity on Microsoft Windows XP Service Pack 2 (SP2) using the native wireless functionality in Windows, called Wireless Zero Configuration (WZC) service.

2. Start the Wireless Zero Configuration service.

Requirements for Service pack 3:

Even though the Wireless Zero Configuration service is set to Automatic, you may find that it is not running, so you will need to start it.

The tool that will allow you to obtain the WLAN profiles as well as deploy them to other machines is called WLAN.exe and is attached to this article.

WLAN.exe has the following command line parameters:

• EnumInterface(ei)
• GetInterfaceCapability(gic)
• QueryInterface(qi)
• SetRadioState(srs)
• GetDriverStatistics(gds)
• Scan(scan)
• GetBssList(gbs)
• GetVisibleNetworkList(gvl)
• SetProfile(sp)
• SaveTempProfile(stp)
• GetProfile(gp)
• DeleteProfile(dp)
• SetProfileList(spl)
• GetProfileList(gpl)
• Connect(conn)
• Disconnect(dc)
• Discover(disc)
• RegisterNotif(r)
• help(?)

Here is a basic example of how you can use this tool, once the Wireless Zero Configuration service has been started.

Capture phase:

1. Enumerate Interfaces - wlan.exe ei

   There are 1 interfaces in the system.

   Interface 0:
   GUID: 89762a5d-bc6b-4ac6-8cf3-b0462b2bafef
   Intel(R) PRO/Wireless 3945ABG Network Connection - Teefer2 Miniport
   State: "disconnected"
   Command "ei" completed successfully.
   
   

2. Get Profile List - wlan.exe gpl 89762a5d-bc6b-4ac6-8cf3-b0462b2bafef

   There are 1 profiles on the interface.

   "Profile1"
   Command "gpl" completed successfully.
   
   

3. Get Profile (profile name is case sensitive) - wlan.exe gp Profile1

   The return profile xml is:

   <?xml version="1.0"?>
   <WLANProfile xmlns="http://www.microsoft.com/networking/WLAN/profile/v1">
   	<name>Profile1</name>
   	<SSIDConfig>
   		<SSID>
   			<hex>574C414E2D445341444B</hex>
   			<name>Profile1</name>
   		</SSID>
   	</SSIDConfig>
   	<connectionType>ESS</connectionType>
   	<MSM>
   		<security>
   			<authEncryption>
   				<authentication>open</authentication>
   				<encryption>WEP</encryption>
   				<useOneX>false</useOneX>
   			</authEncryption>
   			<sharedKey>
   				<keyType>networkKey</keyType>
   				<protected>false</protected>				<keyMaterial>76A3DEC BA383180E8A18E4E522</keyMaterial>
   			</sharedKey>
   			<keyIndex>0</keyIndex>
   		</security>
   	</MSM>
   </WLANProfile> 
   Command "gp" completed successfully.
   
   

Deploy Phase (setting the profile):

wlan.exe sp 89762a5d-bc6b-4ac6-8cf3-b0462b2bafef C:\Profile1.xml

Conclusion:

As you can see, this tool has many functions, and all of them can be scripted in order to allow you to develop an automated method of capturing and deploying WLAN profiles.
