First, take a look at page 6 in the release notes for vSpace 6.6.2.3. Read the section at the top of the page titled 'Windows Multipoint Server 2011'. You will see that there is a reference to the login screen refresh timeout there.

You can use vSpace 6 / 8 MSI install files from the Windows command line to silently install vSpace without user interaction. Note: depending on version of installer, you may need to use the NComputing Cert or the ZeroDesktop Cert. Below is an example of the command line install: msiexec /qn /norestart /i 'NComputing vSpace_L-4.9.5.11.msi' AGREETOLICENSE=yes ADDUSERS=0 DELETELICENSE=0 NComputing MSI Installer and Uninstaller Options: • You must include the 'AGREETOLICENSE=yes' during a silent install to signify that you agree to the NComputing End User License Agreement • The 'ADDUSERS=0' command line option is necessary for silent installs and suppresses the popup window asking if you want to add new users. • The uninstaller now contains a Message Box to provide options for handling an existing vSpace host license during an uninstall. The available license options for use in a silent uninstall/install are: “DELETELICENSE=0” – do NOT remove vSpace license “DELETELICENSE=1” – popup box will appear “DELETELICENSE=2” – remove vSpace license without popup If you encounter the signed driver message popup (shown below), it’s because NComputing’s (ZeroDesktop) code signing certificate hasn’t been stored into the host system’s certificate repository. If you have ever clicked on the “Always trust software from NComputing or “ZeroDesktop.” checkbox (pointed to by green arrow in above image) during an install, then the message will never pop up again on that particular system.

However, clicking that checkbox isn’t a particularly good option for customers desiring to deploy NComputing vSpace on a system for the first time. You can use the following Microsoft command inside your silent install script to import the certificate prior to running the msiexec command: certutil -addstore 'TrustedPublisher' ZeroDesktop.cer Adding the import command similar to shown in screen shot below to your install script will make the install truly silent. Sparkchess.com. (The below image is a representation, and you may be using the ZeroDesktop cert) The Microsoft “certutil” command line tool is included in Windows 7*, and in Windows Server 2008 R2. For vSpace 6.6.2.3 and above, use the file labeled 'NC-code-signing-vSpace 6.zip' for vSpace 8.4 and above use NC-Code-Signing-vSpace8.zip from the file NC-code-signing-vSpace_certs attachment Article: 303.

Thanks for All, I've found a few answers of the End User License Agreement on the vSpace software; c. Microsoft Windows Licenses. You are licensed by NComputing to use the vSpace Software under the terms of the EULA. You must also acquire the appropriate number of Windows Server licenses and Client Access Licenses for each device or user accessing Windows Server software. You cannot use the vSpace Software with Windows Client software (i.e., Windows Vista, Windows 7) unless a single user and no other user accesses the same Windows Client software at any one time, or you are authorized to do so under an applicable license from Microsoft or as expressly set forth below (see “Microsoft Windows Server to Windows XP License Rights”). In all cases, your rights and obligations with respect to the use of vSpace Software with Windows Server software and Windows Client software are defined by both the NComputing vSpace Software EULA and the applicable Microsoft Software License Agreement or EULA. Thanks for the help:-).
