wasabi2k: CCNA is more if you are going the networking route.
MCSA is if you want to work with windows servers.
Roles that do both aren't that common in larger organisations, where you normally split out networks and servers.
Having said that server people that understand networks are twice as useful.
At this early stage of a future career to bottleneck yourself into knowing networking but not Windows and/or Linux server would not be wise. There isn't exactly a lot of huge enterprise setups in NZ. IMO build up a good all around knowledge and then specialize if you feel the need.
