Author SMB over TCP vs. SMB over NBT

Hi,

Found this bit of helpdul info when I got tripped up on a practice Sec+ question.

And I quote:

" The SMB (Server Message Block) protocol is used among other things for file sharing in Windows NT / 2000. In Windows NT it ran on top of NBT (NetBIOS over TCP/IP), which used the famous ports 137, 138 (UDP) and 139 (TCP). In Windows 2000, Microsoft added the possibility to run SMB directly over TCP/IP, without the extra layer of NBT. For this they use TCP port 445. "

Good stuff to know for the test, eh ?

Also wanted to touch quickly on rfc 2196. I gave it a good read once thru. Seems like a lot of info contained in this rfc could match up to what Comptia is after.

See yah,
