            Configuring Firewall and Antivirus for NComputing Products

            Antivirus, firewall, and other types of security software can sometimes interfere with the initial configuration or continued operation of NComputing's vSpace software.  This document gives basic information on applications, services, and network communication within vSpace, which can be used to configure security software and help ensure compatibility and stable, continued operation.

            Possible Symptoms
            • Error: Network Error Code 10014 / Network Error Code 10054
            • vSpace Update Cannot Reach Update Server
            • vSpace Host Not Visible in Connection List
            • Client Hangs (Freezes) During Connection
            vSpace Installation Recommendations

            Please make sure to DISABLE any Anti-Virus or Firewall software during the installation of our product. Software of this type has been tested and known to interfere with the installation of our product.  After installation has completed, you may re-enable Anti-Virus and Firewall software.  

            If system instability occurs after installing NComputing vSpace, please try removing vSpace and any antivirus or security software present, and then reinstalling vSpace.  If the system is stable in this configuration, re-install the antivirus software.  In some cases, this change in install order can improve the interaction between vSpace and antivirus software.  If issues persist, please try configuring your security software to ignore/allow/trust the following ports and executables:

            Summary

            The above exceptions and practices can help ensure the best level of interaction between vSpace and your environment.  If issues still persist with a particular 3rd party application, please contact the application's vendor.  If a workaround exists for your antivirus solution of choice and NComputing engineers have verified its effectiveness, a search for the application's name in the NComputing Knowledge Base will typically reveal any available solutions.
