[Samba] logon problems

[Scott Mayo]

I am really not sure if this is a samba problem or what, but is starting 
to annoy me.  Here is what is happening.

Server 1:  Squid,squidguard,dansguardian,iptables (This is firewall/filter)
Server2:  Samba (used for file storage and squid authentification)
Clients are Windows 98.  A few XP's.

Everything has run fine for almost 2 years.  The other day when trying 
to log on to the internet, it would wait about 20 seconds and return me 
to my logon prompt.  This was for almost every user.  I have one generic 
user that got on all the time.  Another user started getting on after 
about 5 tries and was then able to authenticate each time.  The rest 
still did not authenticate.

When I do:
smb_auth -W DOMAIN -p sambasip -d
it makes it to the last and gives an ERR when giving the contents of 
//server/netlogon/proxyauth.  All the rights are correct and it contains 
the word allow, nothing has changed this for 2 years so it should be 
correct.

When I do:
echo "more proxyauth" | smbclient //server/netlogon -U user
It gives me the contents of proxyauth fine.

I have also noticed that logons start to slow down during the day. 
First thing in the morning they are fast, but then a little later it 
will take about 25 seconds before running my logon scripts. School is 
out, so there are only about 5 people actually here, so it is not 
bogging down the network.  I ran a sniffer and all the traffic looks 
alright.  My authentification will work for a while and then later in 
the day, it will stop again.  I take authentification out of squid and 
then everything gets on the net fine.

I thought that maybe it was a network problem.  So I put 1 WS and the 
Samba server on a hub by themselves and it is still slow to logon.  I 
thought that maybe it was the NIC, but I realized that SSHing into my 
firewall has slowed down also.  So this makes me wonder exactly what is 
going on.  If anyone has any ideas of what to look at, I would greatly 
appreciate any advice.
