OMG! I was hired at a company that had the same infrastructure. The only addition was a CFO that demanded he be able to use his Apple computer. Luck had it that I had a good team under me for the day to day chores and I could concentrate on the CFO and keep him happy, which ensured job security for all.
Yup, it’s good when the higher ups realize that it’s the network that allows the transactions that make the money. We had upper level managers that really appreciated what we did, provided the funding needed to keep us current, and every once in a while, would ask the bankers to cut us some slack.
Like I said, best I.T. job I ever had.
