0x3 0x11 — Rdp

Error 0x3 translates to ERROR_PATH_NOT_FOUND. In RDP, this usually means your client cannot locate the remote computer on the network. It’s a connectivity or name resolution issue, not a credential problem.

Error 0x11 corresponds to ERROR_NETWORK_UNREACHABLE. The RDP client successfully resolved the remote hostname (unlike 0x3) but could not establish a TCP connection to port 3389. The network route is blocked or missing.

Remote Desktop Service failed to load user profile disk for user DOMAIN\username. Error: 0x3 / 0x11

Large RDP packets may be fragmented incorrectly. Aggressive firewalls or VPNs that drop ICMP "fragmentation needed" packets can cause the RDP handshake to time out and log 0x11.

  • Test network access from the RDSH server rdp 0x3 0x11

    net use \\server\share

    If it fails with “network name not found” (0x11), fix connectivity or DNS.

  • Check file existence
    Confirm the .vhdx file for the affected user exists at the expected path.

  • Review NTFS and share permissions

  • Check disk space on the file server hosting the UPDs. Error 0x3 translates to ERROR_PATH_NOT_FOUND

  • Disable UPD temporarily for a test user – if the user can log in, the issue is definitely UPD-related.

  • Event Log correlation
    Look for SMB (Event ID 30800-30806) or disk-related errors around the same time.

    • In RDS or VDI deployments (e.g., Azure Virtual Desktop), if the User Profile Disk (UPD) path points to a missing network share, the session fails with ERROR_PATH_NOT_FOUND (0x3).

    To resolve the "rdp 0x3 0x11" error, follow these steps on the affected Session Host or Licensing Server. Remote Desktop Service failed to load user profile

    Step 1: Verify Licensing Configuration

    Step 2: Check Licensing Server Health

    Step 3: Restart the Licensing Service Sometimes the service simply hangs.

    Step 4: Registry Check (If the server is a Domain Controller) If your RDSH is also a Domain Controller, you must ensure the licensing server is correctly registered in the registry, as discovery can sometimes fail.
