We are currently in the middle of a Windows 7 migration, and we've encountered a strange issue with some of our laptops. When you press control-alt-delete there can be a lag, sometimes small (5-10 seconds) sometimes large (20-30 seconds). Any ideas what might be causing this?
Were are running:
Windows 7 Professional, latest patches
Server 2008 R2
Variety of hardware, HP desktops and laptops, Lenovo Laptops.
