Table 3-1 Niagara hosts in a Microsoft Windows Server Environment.
Windows NT
and Windows
2000 Security
There are two levels of security in a Windows NT or Windows 2000 network. Each
individual Windows NT or Windows 2000 host has local security. Login accounts
that are added to local security have access only to resources on that host when they
are logged on. Windows hosts have two initial local login accounts: Administrator
and Guest.

Operating
System Description
JACE-NP • Embedded
Windows NT 4.0
• Optional: Full
version of
Windows NT 4.0
Since the JACE-NP uses Windows NT 4.0 as its operating system, it operates in an
Windows NT or Windows 2000 environment just like any other Windows NT 4.0 host.
Specifically, it:
• can register with a WINS server for name resolution from other Windows hosts
• supports host name lookup on WINS and DNS servers
• can be a DHCP client
• cannot be a Windows DDNS or Active Directory client
1
By default, each JACE-NP is configured with the following settings:
• is a member of the workgroup named Workgroup
• has an pre-assigned IP address in the range 192.168.1.190-199 and a subnet mask of
255.255.255.0 and a default gateway of 192.168.1.1
• does not have any DNS or WINS servers defined
• is not a member of an Internet domain (for example tridium.com)
• DHCP client is installed but not enabled (see the “Using DHCP” section on page 3-23)
• NetMeeting Remote Desktop Sharing is installed and enabled (Embedded Windows only)
• RAS is installed but not enabled
• SNMP client is installed and enabled (Embedded only)
• the Guest account is disabled
In addition, the RCMD service has been configured and enabled on all JACE-NPs, but is
used primarily with the full version of Windows NT 4.0 (See “Remote Command Utility” on
page 2-5).
Many of these settings can be changed to accommodate the needs of a particular Windows
environment.
Note: The Embedded JACE-NP cannot join a Windows Domain. It also has some
restrictions on adding or configuring resources. For help with configuring an Embedded
JACE-NP, contact Systems Engineering.

JACE-4/5
JACE-5 WindRiver
VxWorks
The JACE-4/5 is not a Windows host and therefore does not support WINS for name
resolution of Windows hosts. However, it:
• supports host name lookup on a DNS server
• can be a DHCP client (see the “Using DHCP” section on page 3-23)
• cannot be a Windows DDNS or Active Directory client.
JACE-4
Engineering PC
Web
Supervisor
PC
• Windows NT 4.0
• Windows 2000
Since this host uses either Windows NT 4.0 or Windows 2000 as its operating system it
operates in an Windows NT or Windows 2000 environment just like any other Windows NT
4.0 or Windows 2000 host. If this host is using Windows 2000, then it has the Windows NT
4.0 functionality plus the capability of being a DDNS and Active Directory client.
