PCs cannot connect to network after upgrade to KES

Recommended Posts

Hi Support Team,

We just upgrade the KES version to and found the PCs with USB port control policy will not able to get the IP i.e. cannot connect to network. 

Reboot the computer or reboot the network card cannot fixed the problem. 

Finally,  we quit the KES and remove the PCs from that "USB port control policy" to get back the network connection.

The questions : 

1. what the upgrade will cause PCs cannot get the IPs? 

2. why the current policy will cause problem when version upgrade?

Looking forwards to your solution. 

Thank you

Hi Ivan, 

We have a Group to limited the USB flash access by KES Policy Device Control.  It was working normally in version 10.3.06294. However,  when we upgrade the version to by KSC, all computer under this group cannot be connected to the network because they cannot get the IP addresses. 

Once we quit the KES on affect computers,  the network connection come back. We finally remove these computers from the USB restricted group to make them online. 

But we really need to USB restrict function. 

Attached the policy capture which was running normally in version 10.3.06294.  Thank you

Thank you for provided data.

Can you please determinate the behavior of KES on affected host bu disabling the components one by one?

We need to understand what component causes this issue.
