I'm not sure why you aren't using FreeBSD here.
Myself, I sit in front of FreeBSD on an Athlon 1200 MHz box complete
with dual head 19" monitors running XFree86 4.1.0 in xinerama mode
so my X server is stretched across the two displays.
This is good in that I can keep the NT world on one display (Windows
Terminal Server via either Citrix ICA, rdesktop RDP or X11 but most
will use RDP due to cheaper licencing) and I can even switch one of
my monitors to its BNC input to use my aging Sparc 10 (which I dont
do anymore since its hard disk died).
I am a NIS client but most of the users who use my machine have local
home directories but I am not averse to having /home/user being a sym
link to /net/expensive-server/export/home/user because I do run amd
solely to provide /net automounting.
I get backed up by HP OpenView OmniBack (as discussed elsewhere
on FreeBSD lists).
I even run the Matrox drivers for my G400 dual head card.
The main thing that's bugging me right now is the NIS client
performance but it appears that no-one on these lists runs a FreeBSD
NIS client (or they do but dont stress their network).
I see that overnight when there is lots of network traffic due to
backups that my periodically run jobs fail to run because NIS cant
get stuff from the server.
The NIS server does coordinate a lot of the backups and is probably
under network load itself at the time.
Most people will say something along the lines of "crummy network",
"crummy NIS server" or something like that to which I'd have to
say "Why dont other people on my network have this problem ?".
Yes these other people are NIS clients.
I can see this poor performance in just trying to start an xterm
under network load and can create 24 -> 32 second delays with a
test as follows:
% cd /usr/ports/distfiles/xc
% ftp nis-server (my home there is local to that box)
ftp> mput *.tgz
Just after pressing enter on the above line, start two xterms.
Now thats quite a bit of data even when myself and the server
are on 100Mbit/s full-duplex switched ethernet links.

The transfers go well with the larger files achieving between
5.14 and 7.78 MB/s however the xterms dont appear until after the
whole FTP mput is finished.
i.e. the timing was:
T+0 I press enter on the "mput *.tgz" FTP command
T+3s I launch xterm 1 from another xterm
T+5s I launch xterm 2 from another xterm
T+25s FTP mput completes
T+27s xterm 1 appears on my display
T+37s xterm 2 appears on my display
Now xterm 1 has the message "yp_first: clnt_call: RPC: Timed out"
as its first line and xterm 2 has two of these messages.
So I'd like to do a little bit of investigation and was wonderring
if other people have some insight as to where to look.
This is not a short term problem and has been present across many
months of -CURRENT (last build 19th September 2001 and typically built
monthly) ever since I became a NIS client about 18 to 24 months ago.
The nis-server runs HP-UX 10.20.
The network is expensive Cisco switched ethernet with everything tied
down to 100 MBit full-duplex at all ends except my FreeBSD box which
is autonegotiating its "3Com 3c905B-TX Fast Etherlink XL" card simply
because I have the line ifconfig_xl0="DHCP" in my /etc/rc.conf and I
dont know how to set media options with ifconfig when DHCPing (anyone
