In some computers, especially older systems and those with slower peripherals,
it may be necessary to delay the loading of a specific Windows NT service for
the computer to boot properly. Or you may want to ensure that one service has
started and is available for use before another for troubleshooting purposes.
This can impact such issues as a domain controller, which cannot access the
network where a protocol, or a service such as DHCP, attempts to load BEFORE the
network card has had a chance to be bound
You create dependencies (that is service A can not start until service X has
started, ie there is a service dependency ), you use the DependOnService value. For details see:
