I'm at a cross-roads here. One direction is as a Windows Server administrator. Mostly virtual servers hosted on VMWare ESX. It entails security, cloning, SAN storage and network configuration. In the other direction is SharePoint 2010 administrator. This would entail managing the actual application and server farm. It would also be a functional position with user and site collection administration and even InfoPath form/workflow development. It would not however involve much .net design or coding.
