Applies to

  • Azure NetApp Files
  • Global File Cache
  • Microsoft Azure


  • End users experiencing slow access to shares on windows host using Global file cache.
  • Takes a long time to enumerate the share contents but eventually they do have access.
  • All Edge servers/sites are affected by the same issue, no recent changes in the environment reported.
  • Reviewing the Global File Cache logs, there are multiple entries of the following licensing deprecated error message:

(Sun Apr  9 10:23:19 2023)    Error    Please check the license key.
