Which of the following protocols would have been affected by this?

My source books don’t have this information. Can anyone point me in the right direction with a source and page number??

Closest thing I have is

nbstat -R (Yes, case sensitive)

This option purges a PC’s NetBIOS cache and reloads entries from a PC’s LMHOSTS file (which is a text file containing NetBIOS to IP address mappings) that have #PRE following the entry. The #PRE option in an LMHOSTS file causes those entries to be preloaded into a PC’s NetBIOS cache.
