1. What sort of network are these workstations and servers connected via?
We are using all Cat5/Cat5e Ethernet connected using 3COM 3300 series switches
2. Are the services running using local (or built-in) accounts, or are
they running under domain accounts?
All of the services are set to use the standard credentials (local system)
3. Are there any messages in the System Event Log concerning these
services not starting (usually from the event source "Service Control
Manager"), and what are they?
We get a couple of errors, the first one is associated with DHCP, but
oddly enough, the client machines still get IPs and the DHCP server
still recognizes their lease as valid and starting at the time the
machine started. The DHCP error is as follows:
Event Type: Warning

We also get an error tht I think is caused by the netlogon service
failing, I am not sure if this error occurs before or after the
failure starts.
