In our configuration, auto-negotiation was a problem only with
Solaris 2.5x and 2.6. There was a patch to resolve the issue,
but Sol 7 and 8 work great, out of the box.
Just my 2 cents.

This may help your PC/NT issues but the /etc/system settings for Solaris are
not addressed in this article. I have seen systems left in autonegiate mode
change settings on the fly (no reboot of either cisco or the sun box).
Dennis,
Changing things in /etc/system will not take affect until reboot. You can
use the ndd commands to set them live. Below are some ndd commands taken
from a couple of sun infodocs:

setting them
# ndd -set /dev/hme instance # <--- set to the Interface in Question
( #=0 for hme0)
# ndd -set /dev/hme adv_100fdx_cap 1 <--- force ON 100Mb full duplex
# ndd -set /dev/hme adv_100hdx_cap 0 <--- force OFF 100Mb half duplex
# ndd -set /dev/hme adv_10fdx_cap 0 <--- force OFF 10Mb full duplex
# ndd -set /dev/hme adv_10hdx_cap 0 <--- force OFF 10Mb half duplex
# ndd -set /dev/hme adv_autoneg_cap 0 <--- force OFF autonegotiation

Actually, the problem is not speed or simplex/duplex auto-negotiation.
On Cisco EtherSwitches, the 10/100 ports negotiate channeling and
trunking by default. The delay caused by channel and trunk negotiation
are what confuses the Sun's HME (or any other 10/100 ) NIC.
If you disable channel and trunk negotiations on the port your Sun
server is attached to, you will see the problem go away.
Here is Cisco's page on the issue:
