Preparing Server for VMS Installation
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.
Limiting 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, go to the System Properties menu located at
Start > Control Panel > System, as shown in figure 2-2.
