    Hello to all...
    For security reasons,i have disabled the following in my XP SP 1 box:
    Network Connections-....File and Printer Sharing
    Network Connections-....NetBios over TCP/IP
    TCP/IP NetBios Helper Service
    Server Service
    Computer Browser Service

    So,ports 137,138 and 139 are closed.Only 445 is still open.
    While googling,almost everyone mentioned setting the extra registry key
    "HKLM\System\CurrentControlSet\Services\NetBT\Parameters" to null,
    some others also mentioned Device Manager-Show Hidden Devices-
    NetBios over TCP/IP-Driver-Startup Type:Disabled.
    What nobody mentioned is what happens if someone closes also the port 445:
    yes,i won't be able to share my stuff
    (big deal,ssl-ftp or ssh cover me for that),but just in case,
    will i still be able to map external shares in xp/2000 boxes,
    or access linux samba shares?
    What i mean is:closing the final port 445 prevents someone from accessing my box,
    or does it also render me unable to access external shares,either win32 or *nix?

    Thanks in advance for any reply...
