Error: Juniper Terminal Services Client could not be initialized properly. Click OK to exit and retry. If the problem persists, please contact Administrator.

Solution:
To resolve the issue, perform the following procedure:
  1. Make sure that the Active X controls and plug-ins are enabled in the browser. Go to IE > Tools > Internet options > Security > Custom Level, and enable the ActiveX controls and plug-ins option.

  2. Mozilla Firefox does not support Active X. However, Java can be enabled. Go to Firefox > Tools > Options > Content, and enable JavaScript.

    Note: To successfully install Juniper components, Active X controls need to be enabled on the Browser and pop-up blocker should be turned off.  

  3. Ensure that dstermserv.exe is not blocked by your anti-virus or firewall program. You can add the dstermserv.exe file to the anti-virus or firewall exclusion list.

  4. The User Account control in Windows Vista and Windows 7 clients, blocks dstermserv.exe; assuming that it is a suspicious file.

    dstermserv.exe implements the Juniper Terminal Services. You can lower the User Account Control settings to allow dstermserv.exe to be function.


Purpose:
Implementation
