That's odd. I see Norton there. Best to disable it temporarily for all SFC-related installations.
Did you install the full version of OP+4? (It has the directory fix in it.)
Alternatively you can just edit the config file manually yourself:
in --> \MetaAssets\ServerProfiles\Multiplayer\WONServerSetup.gf
change it so this section matches the one in your file:
[WONDirectoryServer/Addresses]
0="client.sfc.dynaverse.net:15101"
1="client.dynaverse.net:15101"
2="sfc2.directory.stasis.ca:15101"
