    https://www.mcpvirtualbusinesscard.com/VBCServer/PetarMiljkovic/profile Persistent, highly capable, always willing to learn and eager for challenges! I am Microsoft Certified IT Professional with a certificate in Active Directory management. Besides computers, I love music, writing, love to organize things and always be ahead of others in no matter what I do. My only downside is that I can be very stubborn but in business, it can sometimes be a good thing. I have completed various certification programs such as MCSA, MCSE, MCP, MCITP. During my trainee period I strove towards perfection of managing Active Directory, DNS, DHCP, WINS, relaying, RRAS, Exchange, VPN and all other services provided by Microsoft Server 2008 R2. I did a bit of security as well so IPSec, Firewalls and permissions are of no issues to me. I provide IT administration and support. I'm experienced in troubleshooting common Windows problems, drivers, network issues, virus and malware removal, printers, rollbacks, backups and other common windows issues. My goal is to work in an environment where I can develop myself professionally, learn, and provide the best service I can. Besides networking, my interests are in music production and composing and I love design and photography as well.  less

    I've started as a FreeBSD (and later Linux) system administrator in 1998. This included configuration and tuning of operation systems and various unix services as well as writing custom scripts to automate work and monitor things. Since 2003 my primary area of expertise switched to planning, building and operating networks, mostly based on (but not limited to) Cisco products and solutions, that's why I became CCIE #22125. However, unix-like systems are still part of my life and currenly becoming more and more important for me.  less
