NOTE: Hardware specifications are subject to change without notice.



Minimum Required

Operating System

1 gigabit minimum

Wide Area Network (WAN)

Remote Access (for technical support)

Remote Desktop connection directly into server strongly recommended. Firewall exceptions should be made to allow outbound ports 5500, 5900, and 5901 for Nextech Technical Support to connect to workstations.

External Backup

Customer is responsible for daily automatic backups of entire server with offsite backups weekly.

Windows Updates

Performed on a regular, timely schedule.
