ERROR_NO_BROWSER_SERVERS_FOUND

The list of servers for this workgroup is not currently available

ERROR_NO_BROWSER_SERVERS_FOUND is Win32 error 6118 (0x17E6) and belongs to legacy Computer Browser server-list discovery.

Where the result appears

  • Enumerating servers in a workgroup or legacy Windows domain.
  • Applications using old browse-list APIs.
  • Mixed networks that still depend on NetBIOS broadcasts.
  • A subnet without an available master browser.

Likely causes

  • no browser server supplied a current list for the workgroup.
  • the Computer Browser mechanism is absent on modern Windows.
  • broadcast, NetBIOS over TCP/IP, firewall, or subnet boundaries prevent discovery.
  • the master-browser election or browse list is stale.

Troubleshooting steps

  • Record workgroup or domain name and client subnet.
  • Record API used to enumerate servers.
  • Record NetBIOS over TCP/IP and SMB configuration.
  • Record packet capture for browser elections and announcements.
  • Record whether DNS, Active Directory, or explicit server names work.

What to verify

Verify whether no browser server supplied a current list for the workgroup. Check workgroup or domain name and client subnet together with API used to enumerate servers.

Handling, retry, and recovery

Do not build new discovery logic around the Computer Browser service. Use DNS, Active Directory, explicit configuration, or a supported service-discovery mechanism; troubleshoot browse lists only for unavoidable legacy dependencies.

Difference from nearby codes

The code says the legacy browse list is unavailable, not that every server is offline or unreachable by name.

Practical example

An old inventory tool shows an empty workgroup after SMB1-era browser functionality is removed.
