Following the documented steps to enable CIFS acceleration, but for some reason I am unable to enable the "enable core server" option (same applies to "edge server".
Am I missing something ?
Yeah, you now just use the check boxes like in figure 12.1 here: http://www.cisco.com/en/US/docs/app_ntwk_services/waas/waas/v411/configuration/guide/policy.html#wp1066936
Print services depend on what are you trying to do. I recommend using either the new Windows on WAAS Vitural Blade or Centralized Print Acceleration (again, just a check box to turn it on). The legacy Samba Print services is still available, with almost the same configuration as 4.0.
Hope that helps,
