"IT" is the degree denomination that best fits your expressed desire to focus on server administration (but, do check on serverfault.com: that's where the sysadms hang out!-). In many US colleges you don't have to declare your major at once, so you can try a somewhat more eclectic mix of courses to make sure that, when you do declare, you pick the right one.
As for, what courses are offered, I guess it depends on where you go study! Picking, more or less at random, Missouri Tech (a college I did not previously know about), I see they claim
courses in areas such as systems
analysis, Web applications, several
programming languages, and graphical
user interface design
and that
Graduates of this program will qualify
for employment as entry-level computer
software applications engineers,
computer and information systems
managers, computer systems analysts,
network systems professionals and
computer systems software engineers.
which seems reasonable to me. The required courses are a bit too graphical for my tastes (but then, I am one cranky dinosaur preferring terminal windows and vim to fancy IDEs;-), but don't seem overly specialized:
CAD213 Graphic Design Fundamentals 3.0
CAD233 Web Design 3.0
CAD433 Computer Graphics and Virtual Reality 3.0
CSE303 Systems Analysis I 3.0
CSE353 Systems Analysis II 3.0
CSI243 Information Security 3.0
CSI304 Database Systems 4.0
CSI403 Data Warehousing 3.0
CSP343 Design Patterns 3.0
plus your pick of 3 out of 5 courses which include
CSN253 Network Administration Security 3.0
CSP423 Advanced Visual Basic 3.0
CSP433 Advanced Visual C++ 3.0
CSP443 Advanced Java 3.0
CSP473 Advanced C# 3.0
I notice and bemoan the lack of coverage of fundamental algorithms and data structures, but then, if I understand correctly, this BSIT is intended as a followup to a 2-years Associate degree course in IT which may (I hope;-) hide some such fundamentals in its course... (gaining an Associate degree midway through your Bachelor is not a bad idea -- it gives you more options, after all!-)
