[Samba] Domain unavaliable

First off, I'd like to give all the people involved
with the development of Samba a big thanks.  I'd have
to say that Samba is probably the single most important
piece of software that we run in our research lab.
I'd also like to say that I have had so few problems that
I probably haven't written about one in 3 years.

With that being said, I'm having problems with my
Samba PDC.  I'm running Samba 2.2.8a on a Solaris 8
box.  We have recently moved our lab from one
facilty to another, which forced us to change all
of our system names and IP's.  Luckily, only the
domain part of the name changed, as well as the IP's.

I updated the smb.conf to reflect the new subnet and IP's.  However,
I have recently noticed that people are getting alot of
"Domain LABDOM is unavailable" messages when trying to
logon from Win2k.  This may last anywhere from 2 minutes to 30
minutes.  Then, for no apparent reason, they will be able to logon.

I'm thinking that it has to do with my hosts allow and
hosts deny settings.  Before the move, we were on a subnet
with a netmask setting of  So my hosts allow
setting were this (IP's have been changed to protect the innocent):

hosts allow = 10.0.33.
host deny = ALL EXCEPT 10.0.33.

We are now on a much more restricted subnet, and
can't have the full range to ourselves.  Consequently,
our subnet mask is now, and the IP
address space is from -
(this takes into account the network devices).

I'm wondering if my problem is related to this.
I'm thinking that that I should restrict my hosts
allow with the network/netmask combo:

hosts allow =

Is this what I'm looking for?  I've included the
global part of my conf below.
