Prior to ZENworks 6.5 Support Pack 1 (SP1), the ZENworks Desktop Management Agent installation program created the NAL cache directory (typically, c:\nalcache) and automatically assigned the user Full Control access.
As a result, if you installed the Desktop Management Agent on a workstation, even a locked-down workstation, the installation program created the NAL cache directory and assigned Full Control access, which allowed Novell Application Launcher to access the NAL cache without further modifications to file system rights.
Beginning with ZENworks 6.5 SP1, the ZENworks Desktop Management Agent installation program no longer assigns the user any file system rights to the NAL cache directory (typically, c:\nalcache). Instead, the NAL cache directory inherits whatever rights are assigned to the root of the drive, assuming you use the default location (c:\nalcache). In order for users to be able to access the NAL cache, they need at least Read rights to the NAL cache directory.
As a result of this change, consider the following:
When you install the ZENworks 7 Desktop Management Agent on workstations that had the ZENworks 6.5 (or earlier) Desktop Management Agent installed at one time, you should not experience any NAL cache file system access problems. The original installation created the NAL cache directory with Full Control rights, and the upgrade continues using these same rights.
When you install the ZENworks 7 Desktop Management Agent on a workstation that has not had the ZENworks 6.5 (or earlier) Desktop Management Agent installed at one time, the installation program does not assign any file system rights to the NAL cache directory; it inherits whatever rights are assigned to the root of the drive.
As a result, users might experience problems accessing the NAL cache on locked-down workstations. For example, if users do not have at least Read rights to the root of the drive, they cannot access the NAL cache directory and Novell Application Launcher cannot use the cache.
If you manually created the NAL cache directory and assigned rights before installing the ZENworks 7 Desktop Management Agent or if you changed rights to an existing directory, these rights remain in effect after installation. Be aware that the user needs at least Read rights to the NAL cache, or Novell Application Launcher cannot use the cache.
