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 Typeisabled. 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...
Hi xaros ... and welcome to Wilders If you want to share files/map drives you will need to leave one of the options available.

Hi, xaros sorry to ask another quesktion in your thread, but i was wondering do you still need ANY netbios port open if you are behind a network or a proxy server? Thanx , T
