A machine in my office is extremely slow to respond to certain

going on, when I looked at the capture there is NO TCP traffic. After
a few minutes monitoring (just that IP address) there was only 10
packets, which consisted of ARP x 6, NBNS x 2 and SNMP x 2 while I
was monitoring I browsed the internet and searched for some files on
the network (which all worked, albeit very slowly).

I ran the same sort of test on my machine which came back with 114
packets including TCP and HTTP, I also ran the same thing on another
machine next to the first slow one, which also came back with lots of
TCP packets.
OK, so on which machine are you running Wireshark?  Your machine, one of 
the two other machines you mention, or yet another machine?
