Hi guys,
Recently I've been made more acutely aware of the potential to move up and/or around in the new company I am with (4 months). I've been primarily in the Service Desk/Desktop Support Role for about 15 years now. So I'm experienced with ICT, good with people and solid with trouble shooting IT issues. I'd really like to try and begin shifting into a systems administrator role or at least preparing to move into one if I cannot get any opportunities at work.
Needless I'd like to develop and improve my skills.
The major issue I have at the moment is that I'm rather vague on what the basic functions a system administrator does on a daily/weekly/monthly/quarterly/yearly basis....advice in this area would be appreciated

I'm currently studying a Certificate IV in Frontline Management; I've also got some study material on Active Directory and Powershell to go through before I settle down to do my MCSA 2012. I have a Diploma in Network Engineering.
Advice appreciated....:)
