hi all,
1st time posting here. i stumbled upon this great site by accident (if there's such thing?

). i have no cert however trying to get s+ in the near future and possibly ccna or other certs soon after wards. my background has been mostly application dev and dba, with minor deskside/phone support. i am however changing career path and heading towards security(IT/cyber security in general). i have little exposure to server side admin. i have 3 questions:
a) since i have minor exp with server admin, it's a bit difficult to qualify for a network admin position. so what im looking for in the interim is a help desk/desktop position with a small firm and hopefully interact/assist with the sys admin. is this a good direction? any other suggestions?
b) what are the main roles and how do they fit in the organization for the following:
workstation:
1. help desk , tier 1-3
2. desktop, 1-3
3. it support
server:
1. sys admin
2. sys engineer
3. network admin
4. network engineer
c) what's the most respected cert for the following job roles:
1. for help desk/desktop support: HDI? mcdst? itil?
2. for server: server+? network+? mcse? anything else?
thanks for reading and appreciate any replies.
