DC, Lord - Linked IN name sent.
I've tried to make it complete, but I'm not sure it really shows the full Jack-of-All-Trades aspect of what I did. Being a central Service Desk, we handled some aspect of everything from basic MS Office questions through the fun stuff - confidential HR terminations, internal application support, hardware and software troubleshooting, network, IP and VPN troubleshooting, documentation, training, mentoring, change control, process and policy creation, SLA and metric creation and monitoring, etc.
We did just enough of everything to have a clue and be able to fix most things, but large company siloing of functions kept us from getting into any of it deep enough to really be proficient in depth. As an example, I could fix all but one aspect of a hybrid hosted Exchange user account, but that one aspect was often the one keeping the account from working. We could pinpoint a synchronization failure between DNS and some of our DHCP servers, but we could not fix it. We were the ones to diagnose that the RSA security DB replicas had stopped syncing, but were not able to restart the sync. It got a bit frustrating trying to convince the people in those silos that their stuff was broken when they hadn't noticed anything wrong.
Don't get me wrong. I LOVE being a Jack-of-All-Trades type of tech. It provides a wonderful perspective and the ability to visualize an entire process, then drive it from design to implementation. It was the limits that chafed - only being able to do these things for internal department projects but running into political roadblocks if we wanted to extend them any further.
