I supported users as second line help desk but a few months later I got opportunity to work for customer project account which was same, but the expectations was more higher to ensure the correct business continuity. My knowledge and agile attitude helped to be good specialist in this new challenge. We supported Windows XP and 7 workstations and controlled the users and computers with domain accounts. In this company has been working more than 2500 people, so ticketing tool helped me to organize my daily tasks. The users problems were usually network errors, program bugs, program installation, driver errors, printer installation, IP phone configurations, Lotus Notes and MS Office errors, Citrix, SAP, Hummingbird, Livelink, RSA soft token, Socks, Cisco and AT&T vpn configurations, virus buster or domain account problems. The configurations were different on every project accounts. When a configuration had been changed by the project owner, we had to fix it on the account immediately occasionally more than 100 workstation. When a new account started we had to prepare for it: collect the instructions which programs would use and what kind of configurations needed. In 2013 I got opportunity to work on Cemex external project account, which was outside of IBM buildings and use their own network, servers and tools. I with my team had to ensure in this circumstances the business continuity.
