Right now I am using Agent as newsreader and its retreiving messages -
no problem

My browswer has stopped retreiving pages - no server

A dos window - can ping my DNS server(s) and ping other addresses
but can not ping by host name

This prioblem has been going on a while now, I have had the system up
and connected to ISP for several hours, and have had the connection
timeout and restart several times in that period

All with no problem.

ANy ideas ?

What if a timeout occurs in a DNS lookup - to both servers

Does Win98Se remember this and fail to lookup after this point

You see th ereal problem is that when Agent has finished its retreive
it will disconnect and not be able to re-establish a conenction again.

I will actually have to reboot to resolve (!!) the problem

Do you use a firewall or anything that could stop UDP packets?

You could use a packet logger set to UDP port 53 and then set your
connecton DNS server to 127.0.0.1 and then try DNS resolution. They
won't resolve but you will see if your software is asking the DNS server
anything.

There is a negative DNS cache timeout in the registry somewhere. I heard
a program called TCPOptimizer that allows you to enter anything you wish
there in a field and apply it. That's simpler than digging in the
registry IMHO. You'll want to set that setting to 0 to make sure Windows
does not cache anything of that.

In command prompt:

ipconfig /release_all
ipconfig /renew_all

Hope this helps.

update: (ie still not resolved ....)

I realised that I had a 2nd unused local network connection with ip
etc
Thought that this may mess up DNS after timeouts.
Also something about NETBIOS doing name resolving ..

anyway dropped 2nd network, in doing so Win98Se reinstalled tcpip set
up (I think) and noted I was about to install an older copy of
rcp...dll (this is the module that actually does the dns calls isn't
it ?)
I let it put the old one back.

for a few days this has been better - no loss of DNS

until a while back, so this hasn't fixed it.

anyone any ideas ??

(lucky bonus for 2 years my PC has not restarted on shutdown, I always
have to power off and back on again - now it works, I only dropped the
tcpip stack on the 2nd card - odd )

(1) This does not appear to be a fit/proper response to Jur Sah's post,
which you did promise to do. And he is waiting patiently 10 days now!

(2) I do know I had NET connection problems for quite a while back when
McAfee went batty with it's Auto-System Scan. Try turning yours off to
see the immediate & dramatic improvement. Then, get back to me for the
fix, which is to update it's scan engine by taking a SuperDat.

(3) Pore through Agent's menus/options for something that can adjust
when it will disconnect/time out.

(4) Try removing/re-establishing your Network software. Begin at
"Control Panel, Add/Remove Programs, Windows Setup tab, Communications
component".

will do so
brief answer here -
I firewall is ok, a tcp data logger shows dns request being made to
port 53 as expected.
It showed them timing out - and some netbios calls as well
hence removal of 2nd network card (in case this confused)

ipconfig /release had no apparent affect, ie ipconfig / all gave same
results before and after the /release_all and again after the
/renew_all - and still dns didn't work

I don't run McAfee or any live AV
I run frequent Standalone checks - nothing ever found in last 3 years
I run a tight firewall - Tiny's Personal Firewall

this may be possible, but wouldn't prevent something dropping the DNS
resolving - just allow me to keep a nttp port open longer

I did this for the 2nd card - it backdated the rcp..dll file
I suppose I could for broke and remove / re load them all

Look for a setting somewhere to control timeout, such as in... "Control
Panel, Modems, General tab, highlight the modem, Properties button,
Connection tab".

For other complaints, that usually works but doesn't last.

Seems that's not the problem, then.

I do know IE has settings, but these may ultimately get to the modem
Properties. Also, there is a setting to disconnect upon closing the
browser.

Here is an article to look through...
http://support.microsoft.com/default.aspx?scid=kb;en-us;166832&Product=w98
Err Msg: Cannot Find a Device File That May Be Needed to Run...
(166832) - When you restart your computer after installing the Dial-Up
Adapter, you may receive the following error messages: Cannot find a
device file that may be needed to run Windows or a Windows application.
The Windows registry or SYSTEM.INI file refers to...

And here are my settings...
It wasn't too tough in "Control Panel, Network". Let me see whether I
can find my final setup...

A. Configuration tab

Primary Network Logon: "Client for Microsoft Networks" is selected in
the dropdown menu.
File & Print Sharing button: Neither is checked.
These components are installed...
(1) Client for Microsoft Networks
Properties: Only "Logon & restore..." is bolted.
(2) Dial-Up Adapter
Properties:
(a) Driver Type tab: Only "Enhanced mode..." is bolted.
(b) Bindings tab: Only TCP/IP is present & checked.
(c) Advanced tab:
1. Enable Point To Point IP: Yes.
2. IP Packet Size: Large
3. Record a log file: No.
4. Use IPX header compression: No.
(3) TCP/IP
Properties:
Bindings tab: Only "Client for Microsoft Networks" is present &
checked.
Advanced tab: Allow Binding to ATM: No.
NetBIOS tab: "I want to enable..." is checked but shaded.
DNS Configuration tab: Disable DNS is bolted. Rest is blank.
Gateway tab: Looks blankish.
WINS Configuration tab: Only Disable WINS Resolution is bolted.
IP Address tab: Only "Obtain an IP address automatically" is
bolted.

(B) Identification tab

(1) Computer name: Computer.
(2) Workgroup: Workgroup.
(3) Computer Description: Unknown User.

(C) Access Control tab
Only "Share level access control" is bolted.

I thought I knew what I was doing at the time I set it up like that. I
trust I was just about right.
