Clipboard operation prohibition applies in the following cases:
When the remote desktop connection is used to establish a remote connection
When Citrix Receiver is used to connect to Citrix Xen App or Citrix Xen Desktop
When VMware View Client or VMware vSphere Client is used to connect to VMware (Horizon) View or VMware vSphere
Information delivery from the virtual environment to the physical environment or from the physical environment to the virtual environment via the clipboard will be prohibited, while the delivery from the virtual environment to the virtual environment or from the physical environment to the physical environment will not be prohibited.
When information is extracted from the clipboard through pasting, the operation of saving information to clipboard (copy, paste) will not be prohibited or recorded.
During clipboard operation of text data, the maximum size of the original file that can be saved is 2048 halfwidth characters (1024 fullwidth characters). If the size is larger than 2048 bytes, the excess part will be truncated.
When continuing with a clipboard operation after copying, the prohibition log after the second clipboard operation will not be sent in the copy source.
When the remote desktop or Citrix Online Plugin is used, a prohibition log will be output when the right-click context menu of explorer at the copy destination is displayed. If the copy sources are in the same environment, no prohibition log will be output.
Multiple prohibition logs will be sent for one paste operation.
If a clipboard operation from a virtual environment to a physical one is attempted and prohibited, the log application name sent from the copy source virtual environment will be blank.
When an image is pasted to Microsoft Excel, the original file will not be original file backup.
When a virtual environment client other than remote desktop is used, the name of PC at the copy destination in the copy source log is blank.
The PC name of copy destination cannot be obtained in the environment in which remote desktop is used and IPv6 is effective.
When a file is being copied, the original backup file name of the copy source is the file name with path, while the file name of the copy destination is the file name only.
When Microsoft Word or Microsoft Excel is used in the virtual or physical environment, clipboard operations can be performed within the Microsoft Word or Microsoft Excel after the window has been activated. Therefore, the relevant prohibition log will be recorded.
When logging off the Citrix Online Plugin, the relevant clipboard prohibition log will be recorded.
When VMware View Client/VMware vSphere Client is used, data can be obtained from the clipboard when switching between the window of physical environment and virtual environment. Therefore, the relevant prohibition log will be recorded. In addition, the prohibition logs at the copy source and destination are different.
When text data is copied and pasted within an application, the line feeds in the Content column will be replaced with "??".
When the Citrix Online Plugin is used, the PC name of the physical environment is blank in the log of virtual environment.
When VMware View Client/VMware vSphere Client is used, the PC name of the physical environment in the virtual environment is blank and the PC name of the virtual environment in the physical environment is blank.
If remote desktop is used, the path name of cache data will be recorded in the Content column in the physical environment log after a file has been copied from the virtual environment to the physical environment according to the following operations.
Operation
After performing the paste operation before the clipboard operation prohibition policy has been set, set clipboard operation prohibition on the client (CT). Then, copy the file from the virtual environment to the physical environment.
A "virtual desktop" feature that allows you to start up multiple desktops and perform different operations on each desktop has been added in Windows 10.
This "virtual desktop" does not involve operations between a virtual environment and physical environment, but instead, involves operations between physical environments. Therefore, clipboard operations cannot be prohibited.
Clipboard operation cannot be prohibited when pasting operation is performed for Windows 8.1, Windows 10, Windows Server 2012, and Windows Server 2016.
