0X0000083B: The Device Isn't Connected – Fix It Now

1. The Printer or Shared Drive Isn't Actually Turned On or Connected to the Network

I know this sounds painfully obvious, but I can't tell you how many times I've driven across town to find a client's HP LaserJet sitting in standby mode, or a shared USB drive that got unplugged by the cleaning crew. The error 0X0000083B is Windows's way of saying "I can't see the device anymore." Before you dig into settings, check the hardware.

Here's what to do first:

• Look at the printer or external drive. Is it powered on? No blinking amber lights? If it's a printer, see if it's displaying an error message like "Paper Jam" or "Offline."
• If it's a network share (like a folder on another PC), make sure that PC is turned on and awake. Had a client last month whose whole office file share stopped working because somebody disabled the power settings on the host machine.
• Check the network cable if it's wired. Push it in until you hear a click. Wi-Fi? Check the device's network status—some printers drop the connection after a firmware update.

The fix: Power cycle the device. Pull the plug for 30 seconds, then plug it back in. Wait two minutes for it to fully boot. Then try again. If you still get 0X0000083B, move to the next cause.

2. Windows SMB Protocol Mismatch (Most Common for Shared Drives and Older Printers)

This one's the real culprit about 60% of the time. Windows 10 and 11 disabled SMB 1.0/CIFS by default after the WannaCry ransomware mess in 2017. But a lot of older network drives and printers (especially those from 2012 or earlier) still rely on it. When you try to connect, Windows throws 0X0000083B because it can't negotiate a protocol.

Real world: Last year, a small accounting firm called me because their brand-new Windows 11 laptops couldn't access a shared folder on an old Buffalo NAS. Every time they clicked the drive letter, they got 0X0000083B. The NAS only spoke SMB 1.0. I enabled it, and they were back in business in 10 minutes.

How to fix it (proceed with caution):

1. Turn on SMB 1.0 support – Only do this if you're sure the device needs it. Open Control Panel, go to Programs and Features, click Turn Windows features on or off. Scroll down and check SMB 1.0/CIFS File Sharing Support. Expand it and also check SMB 1.0/CIFS Client. Click OK and restart.
2. If that feels too risky (and it's a fair concern), update the device's firmware instead. Check the manufacturer's support page. Many older devices got patches to support SMB 2.0 or 3.0. I've seen Brother printers and Synology NAS units get firmware updates that fixed 0X0000083B without enabling SMB 1.0.
3. As a last resort, map the drive using the IP address instead of the hostname. Open File Explorer, right-click This PC, select Map network drive, and enter \\192.168.1.100\sharename (replace with your device's actual IP and share name). This bypasses some name resolution issues that also trigger 0X0000083B.

3. Network Discovery or Credential Cache Got Corrupted

This cause is sneaky because everything looks fine—the device is on, the cables are snug, SMB is set up—but Windows still won't connect. The problem is usually a corrupted credential cache or a network discovery setting that flipped off during a Windows update.

Here's the fix sequence I use:

Step 1: Clear Stored Credentials

Windows remembers old usernames and passwords for network shares. If those are stale or wrong, you'll get 0X0000083B even though the device is perfectly fine.

1. Open Control Panel > Credential Manager.
2. Click Windows Credentials.
3. Look for any entries related to the printer or network share. If you see them, click the arrow and select Remove.
4. Restart your PC and try connecting again. Windows will prompt you for new credentials if needed.

Step 2: Turn On Network Discovery

1. Open Settings > Network & Internet > Advanced network settings (or in older versions, Network and Sharing Center).
2. Click Network and Sharing Center (if not visible, search for it).
3. Click Change advanced sharing settings.
4. For your current profile (usually Private), turn on Network discovery and File and printer sharing.
5. Make sure Turn off password protected sharing is selected—unless you want to enter a username every time. I usually leave it off for small offices.

Step 3: Reset the TCP/IP Stack (Nuclear Option)

If nothing else works, open Command Prompt as Administrator and run these commands in order:

netsh int ip reset
netsh winsock reset
ipconfig /release
ipconfig /renew
ipconfig /flushdns

Restart the PC after. This clears any corrupted network settings that Windows quietly accumulated. I've used this on a dozen machines and it's fixed 0X0000083B when all else failed.

Quick-Reference Summary Table

If you've tried all three and still see 0X0000083B, it might be a hardware failure. Try connecting the device to another computer. If it works there, wipe the network settings on the problematic PC. If it doesn't work on any PC, replace the device's network interface card or the device itself.
