We have a client that we swapped out their old 2003 SBS out for a 2012 Essentials server, we also swapped out all of their XP work stations with Windows 7 professional work stations.
Since the swap the client is complaining of slowness across their network (lan wise).
Their quickbooks software takes a while to load up, when it was almost instant
Print jobs to network printers take about 45 seconds to do, when they useto take 10 seconds at most.
Their new server is configured as a DNS & DHCP server as well if that matters, any ideas would be greatly appreciated!
