Some of many windows utilities that I use:
wget win32: http://users.ugent.be/~bpuype/wget/ I like to add a file association with a custom open action that runs wget like this:
C:\path\to\wget.exe -nd -nH -c -i "%1" | pause
Then when you have a lot to download you can create a .wget file and winhose will know what to do when you double click or 'run" the file from a script.
NcFTP:
http://www.ncftp.com/ncftp/ Great commandline ftp client suite. Great for scripting (ncftpput/ncftpget)
TFTPD32:
http://tftpd32.jounin.net/ This little beauty is about the nicest tiny tftp server I've come accross. Also has tftp client, sntp server, syslog server, and dhcp server. All services can be enabled/disabled as you need.
Dig:
http://www.isc.org/sw/bind/ Better than nslookup. Download the whole bind nameserver package and then copy the following files out to somewhere on your path:
dig.exe
bindevt.dll
libbind9.dll
libdns.dll
libeay32.dll
libisc.dll
libisccc.dll
libisccfg.dll
liblwres.dll
Common usage:
dig [@some.nameserver.ipaddy] [host.]example.com [mx | any | a | etc...]
The @xxx.xxx.xxx.xxx argument causes dig to query that specific nameserver
