Make sure you have the command prompt open by searching for “cmd” or “command prompt” in the Start menu.
Type the command you see below and scroll down to the network adapter corresponding to the connection you are using. Note down the default gateway, subnet mask, MAC address, and DNS address.
ipconfig /all
Then, using the Windows + R key combo, immediately open the “Run” dialog box, type “ncpa.cpl” in the bar and tap “OK” to bring up the Internet Connection Settings section of the Control Panel.
Double-click the active network adapter and click the “Properties” button. The Internet Protocol Version 4 (TCP/IPv4) item will appear. Tap to select that item and click the “Properties” button.
While still in the General tab, switch the radio button in the Properties window to “Use the following DNS server addresses”: 8.8.8.8 and 8.8.4.4, respectively. Switch to “Use the following IP address” and use the same number as the default gateway, but change the digit after the last dot to something else. Fill in the other information as you took notes.

Edit a Configuration File

Editing a file that holds the game’s configuration settings is another successful way to get rid of the problem. The server the game uses to connect is what you are about to change. It’s set to “default,” but the server you’re trying to connect to might be far away or have problems.

Open the “File Explorer” on your computer and click on the “Documents” entry in the left navigation pane and navigate to it. Open the “My Games” folder in it.
Double-click on the folder named “Rainbow Six – Siege” to open it. Also locate the file named “GameSettings“. Right-click on this file and select “Open with >> Notepad” from the context menu to edit it.
Scroll to the bottom of this document and find the “Server” setting. The default is “default.” Change the value next to it to a 3-letter code that represents the server. A list of available servers will appear, select the one closest to you; press Ctrl + S to save your changes.
Try running the game again to see if the Rainbow Six Siege Error Code 3-0x0001000b continues to occur after following these steps.
