Prepare Server for VMS Installation
The Vipersat Management System Server software should be installed on a
high-performance, industry-standard computer running the Microsoft Windows
Server 2008 or later operating system.
If not already done, perform the following tasks before proceeding with installa-
tion of VMS on the server:
• Limit DEP (Data Execution Prevention) — see following section.
• Create a user account in the Active Directory (example: VMS).
• Add the VMS user to the DCOM Limits.
• Reboot the server before continuing with the VMS installation.
Limit DEP (Data Execution Prevention)
DEP (Data Execution Prevention) is a service, available on some CPUs, which
will actively block a virus or program which it determines acts like a virus.
Without limiting the action of the DEP feature to essential Windows programs
and services, this procedure will prevent DEP from blocking the actions associ-
ated with VMS.
Use the following procedure to make certain that this feature is limited to essen-
tial Windows programs only.
1. From the server’s Start menu, open the System control panel located at
Start > Control Panel > System , as shown in figure 2-3.
2. Click on Advanced system settings to display the System Properties dialog
page shown in figure 2-4.
