Figure 12-4 Synchronizing Time on NetWare 5.0 and 4.2 Servers
Therefore, if you have NetWare 4.2 or 5.0 servers in your eDirectory tree, and you want to install an
OES 2 server, you must have at least one NetWare 5.1 or later server to provide a “bridge” between
NTP and Timesync time packets.
Figure 12-5 on page 102 illustrates that these earlier server
versions can synchronize through a NetWare 6.5 server.
IMPORTANT: As shown in Figure 12-4 , we recommend that NetWare 4.2 servers not be used as a
time source.
OES 2 Servers as Time Providers
Figure 12-5 shows how OES 2 servers can function as time providers to other OES 2 servers and to
NetWare servers, including NetWare 4.2 and later.
