It's useful to know...
1. the exact platform used for the server
2. the config of the clients, are they diskless or is bootp just a way to manage configuration?
3. Are you using a dynamic or static IP allocation scheme?
4. If static, have you got all the MAC addresses, and are they all on the same subnet as the server?
The first step is normally setting up the "/etc/ethers" file which maps MAC address to hostname.
And make sure the name resolving works, typically by "/etc/hosts".
Then you need additions in "/etc/bootparams" which map hostname to root file, swap file and dump file.
You need NFS started for clients to access shared directories.
You need tftp enabled for clients to load their kernel
You need [rpc.]bootparamd started in order for client to get rest of boot up configuration.
I suggest enabling debugging on TFTP server so you can monitor what clients are doing and what kernels they are requesting.

bootparamd
rpc.bootparamd(1M) System Administration Commands rpc.bootparamd(1M)
NAME
rpc.bootparamd, bootparamd - boot parameter server
SYNOPSIS
/usr/sbin/rpc.bootparamd [-d]
DESCRIPTION
rpc.bootparamd is a server process that provides information from a bootparams database to diskless clients at boot time. See bootparams(4)
The source for the bootparams database is determined by the nsswitch.conf(4) file (on the machine running the rpc.bootparamd process).
OPTIONS
The following options are supported:
-d Display debugging information.
FILES
/etc/bootparams boot parameter data base
/etc/nsswitch.conf configuration file for the name-service switch
ATTRIBUTES
See attributes(5) for descriptions of the following attributes:
+-----------------------------+-----------------------------+
| ATTRIBUTE TYPE | ATTRIBUTE VALUE |
+-----------------------------+-----------------------------+
|Availability |SUNWbsu |
+-----------------------------+-----------------------------+
SEE ALSO
svcs(1),svcadm(1M), bootparams(4), nsswitch.conf(4), attributes(5), smf(5)
NOTES
A diskless client requires service from at least one rpc.bootparamd process running on a server that is on the same IP subnetwork as the
diskless client.
Some routines that compare hostnames use case-sensitive string comparisons; some do not. If an incoming request fails, verify that the
case of the hostname in the file to be parsed matches the case of the hostname called for, and attempt the request again.
The rpc.bootparamd service is managed by the service management facility, smf(5), under the service identifier:
svc:/network/rpc/bootparams
Administrative actions on this service, such as enabling, disabling, or requesting restart, can be performed using svcadm(1M). The ser-
vice's status can be queried using the svcs(1) command.
