WPA2-Enterprise/AES/PEAP Wifi connection causing Host Process/Windows Explorer Crashes
System information is at the end of this forum.
I am working on solving IT problems with a wireless network on a College Campus. We use the following settings:
Security Type: WPA2-Enterprise
Encryption Type: AES
EAP Type: Protected EAP (PEAP)
Connect to these Servers: we use two different servers
Trusted Root Certification Authorities: GeoTrust Global CA
When setting up the connection on this system, I select and enter the proper Security/Encryption type, however I am not given the option to edit the Protected EAP Properties and therefore windows is unable to trust the Root Authentication Certificate from
GeoTrust Global CA as the connection server is not trusted by default in windows. Because of the above, when connecting using automatic settings I receive an error from windows stating windows does not have the proper information to accept Certificate
from GeoTrust Global CA. The steps taken in this process are listed below.
When attempting to set up the connection manually I receive an error Windows Explorer has Stopped Working
Error Description states "explorer.exe: The instruction at 0x734cc061 referenced memory at 0x00000000. The memory could not be read. Click OK to terminate the program.
The steps taken to duplicate this error are listed below as well.
In addition we also have a utility that creates the wireless profile, however after the proper settings are configured I then receive an error stating "Host Process for Windows Services stopped working and was closed”. After this message is received
the system cannot see any wireless connections unless either the system is restarted or the NIC is disabled and enabled via the Device Manager.
Steps taken to produce issues:
Open Network and Sharing Center
Click Set up a Connection or Network
Selected "Manually Connect to a Network"
Click Next
Typed SSID
Selected WPA2-Enterprise
Selected AES
Click Next/Finish
Receive Connecting to SSID
Receive Error: Windows Explorer has Stopped Working
Error Description states "explorer.exe: The instruction at 0x734cc061 referenced memory at 0x00000000. The memory could not be read. Click OK to terminate the program.
Right click on Network Notification in System Tray
Click Connect to a Network
Select proper SSID
Receive Prompt for username/password/Domain
Receive Notification stating windows does not have the proper information to accept Certificate from GeoTrust Global CA
Click OK
Receive notice: Connecting to SSID
Receive Error "Host Process for Windows Services has Stopped Working and was closed

Hi,
The error message "Host Process for Windows Services stopped working and was closed" indicate one of the dll file might get corrupt during the process. It may occur due to conflict with your driver and certain application.
Please make sure you have the latest Network card driver installed.
In case certain third party software trigger conflict with the driver, I suggest prepare
clean boot to troubleshoot.
