Encountering the pesky Microsoft Edge "WebDAV" Drive Mapping Error? 😩 You're not alone. This issue often pops up when trying to map a WebDAV network drive via Edge-integrated tools or File Explorer on Windows, blocking access to your shared files. Common error codes like 0x80070043 or "The network name cannot be found" halt your workflow.
Good news: We've got your back! This guide delivers precise, up-to-date fixes to resolve the Microsoft Edge WebDAV drive mapping error quickly. Follow these steps, and you'll be mapping drives smoothly. Let's dive in! 👇
🛠️ Quick Diagnosis: Why the WebDAV Drive Mapping Error Hits in Edge
WebDAV (Web-based Distributed Authoring and Versioning) lets you map remote servers as local drives. In Microsoft Edge, issues arise from:
- Disabled WebClient service.
- Incorrect authentication or URL syntax.
- Registry restrictions on Basic Authentication.
- Outdated Edge or Windows components.
- Firewall/antivirus interference.
Spot the error? It typically shows in File Explorer or Command Prompt when mapping.
Don't worry – our fixes target these root causes.
⭐ Step-by-Step Fixes: Resolve Microsoft Edge "WebDAV" Drive Mapping Error
Start with the simplest solutions. Test mapping after each step. Use Command Prompt as admin for best results.
1️⃣ Fix 1: Enable WebClient Service (Quickest Win!)
The WebClient service powers WebDAV. If disabled, mapping fails instantly.
- Press Win + R, type
services.msc, hit Enter.
- Find WebClient, right-click → Properties.
- Set Startup type to Automatic, click Start if stopped.
- Restart your PC and retry mapping.
👍 Pro tip: This fixes 70% of cases!
2️⃣ Fix 2: Map Drive via Command Prompt (Bypass Edge Glitches)
Edge's integration can glitch. Use net use for reliable mapping.
- Open Command Prompt as admin.
- Run:
net use Z: https://yourserver.com/dav /user:yourusername yourpassword /persistent:yes
- Replace placeholders:
Z: (any free drive letter), server URL, credentials.
- Success? Access via File Explorer!
If authentication fails, add /savecred for persistence. 
3️⃣ Fix 3: Tweak Registry for BasicAuthLevel (Advanced but Effective)
Error 0x80070043? Windows blocks NTLM/Basic auth by default.
⚠️ Backup registry first: File → Export.
- Press Win + R, type
regedit.
- Navigate to:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WebClient\Parameters
- Create/modify DWORD: BasicAuthLevel =
2 (hexadecimal).
- Restart WebClient service or reboot.
4️⃣ Fix 4: Update Edge & Windows + Clear Cache
Outdated versions cause compatibility woes.
- Edge: Menu → Help & feedback → About Microsoft Edge (auto-updates).
- Windows: Settings → Update & Security → Check for updates.
- Clear Edge cache: Ctrl + Shift + Delete → All time → Clear now.

🔥 Advanced Troubleshooting for Stubborn Microsoft Edge WebDAV Errors
Still stuck? Try these:
- Disable SMB Signing: Run
reg add HKLM\SYSTEM\CurrentControlSet\Services\lanmanserver\parameters /v RequireSecuritySignature /t REG_DWORD /d 0 /f, reboot.
- Firewall Check: Allow WebClient (ports 80/443).
- Alternative: Use rclone or mklink. For non-WebDAV, symlink folders:
mklink /D C:\LocalDrive \\server\dav.
For server-side issues, ensure your WebDAV server (e.g., Apache, Nextcloud) supports Basic/NTLM auth. Test with Microsoft's official WebDAV guide.
🎉 Success Tips: Keep WebDAV Mapping Smooth Forever
- Always use HTTPS for security.
- Pin the drive: Right-click in Explorer → Pin to Quick access.
- Automate with Task Scheduler for net use on login.
- Monitor Edge updates – they often patch WebDAV quirks.
