Windows 10: 2004 Update breaks 802.1x DHCP IP address assignment

After the last major update, our Ethernet connection doesn't work as before when obtaining a IPv4 address assignment from our Windows 2016 DHCP server. The issue affects all our pc from different vendors. When a domain user authenticates to start a new session, he doesn't receive the correct ip and gateway address, so he cannot have access to the network because the pc stays in a VLAN where that ip doesn't work. The problem needs to be fixed by disconnecting and reconnecting the ethernet cable, then it is stable for the time of the session. After a reboot or a logout, the problem starts again. We have this problem on all the pcs in the LAN after 2004 update.

We tried, with no success, to do the following:

- ethernet driver update (Intel);

- uninstall and reinstall ethernet interface;

- disable IPv6 from network properties;

- install a previous ethernet driver version (Intel);

- disable energy saving properties in ethernet interface;

- disable realtime antivirus functionalities;

- check correct operation at Radius and DHCP server level.

Any further idea about how to fix this issue?

Thank in advance for any help.

Assigning Static IP Address Range in a Router

yep, pretty much all.

for point #2 if you are having difficulty binding static IP in the router, it is ok to set static IP in the camera instead - just make sure you take a note on which IP is which camera so that you wouldnt put the wrong IP in the port forwarding.

am not sure what you meant. you don't need ddns to access the camera locally (from inside your LAN) *Confused

 

Finding IP address

Hello,

Thank you for writing to Microsoft Community Forums.

I suggest you to follow the steps mentioned below to find printer’s IP address:

1. Type Devices and Printers in the Windows search bar.
   
2. Select on the printer and click on
   Manage.
   
3. Click on the Ports tab.
   You will be able to find printer’s IP address under the ‘Ports’ tab.
   

Few printers also have a “Test print” option on the printer. When you print a test page from network printer, the page shows the IP address along with other details.

Note: If it is set on DHCP mode the IP address will constantly change.
The IP address is assigned automatically by your router using a protocol called DHCP.

Hope it helps.

Assigning Static IP Address Range in a Router

Shorten your DHCP range and use an address outside that range, it will still ARP the IP and add it to the table, but never allocate the IP from the open pool.


So

DHCP range 192.168.0.1-150

Static IP's begin and are assigned to devices at 192.168.0.151

Simple.
