What To Do

You need to check whether you are able to connect to Sophos Live Protection (Sophos cloud).
You can do this by downloading a purpose built tool which will check your connection, or you can check it from the command line.

1. Checking for the connection

To use the Sophos Live Protection checking tool:
  1. Go to http://downloads.sophos.com/tools/slptest_sfx.exe, download the tool, and save it to a convenient location.
  2. Double-click to run the tool. It will report back with the following information:
    • 'Test passed' or 'Test failed'
    • The time taken for the SXL lookup.
To check the connection from the command line:
  1. Run the following command from a command prompt
    nslookup -type=TXT test.00.s.sophosxl.net
  2. The response should be similar to
    Server: hostname.domain.name
    Address: 192.168.1.224
    Non-authoritative answer:
    test.00.s.sophosxl.net
    text =
    "WORKING"
2. What to do next
  • If you do not have a connection, check that your DNS configuration settings are correct , and if not, adjust them accordingly. Then re-run the test.
  • If the above tool shows you do have a connection and your DNS configuration settings are correct but a scan is still running slowly contact Sophos Technical Support for help.
