Wincows network display times dragging

R

reader

Setup: Home network running 3 winxp pro machines 1 winxp home laptop.

I've been experiencing this trouble for a good while (mnths) but
finally annoyed enough by it to dig in and try to find the problem.

Using windows native networking tools, I find response times to
clicking in `network places' to be annoyingly slow. Upwards of a minute
before a host appears.

Typing UNK names directly into windows explorer like:

\\host... takes a little less but hardly noticably less.

Clicking on the Network Neighborhood then the home network usually
fails to display all hosts.

Some kind of nagging irritatingly slow response exists on every host.
My Network is setup with IP numbers not dhcp thru a router that sets
inside the Internet connection.

INTERNET/modem/router - home network router - network

Every host has its seperate IP number, and the same gateway. Gateway
is also dns server for every host.

How can I pinpoint this problem?

Look at the network stack on each computer. Examine and compare logs from
"browstat status" and "ipconfig /all", from each computer. Read this article,
and linked articles, and follow instructions precisely (download browstat!):

Describe the LAN in more detail. Are you using fixed (pre-assigned) IP
addresses, or are they assigned by the router? How many computers use Ethernet?
WiFi? Make and model of network hardware please.

Have you tried "\\hostIPaddress", as opposed to "\\hostname"?

You've given me quite a lot to digest... thanks for the good pointers
However `nitecruzr' is not loading for me. I suspect there is some
network mess between me and it.

Let me just ask for some clarification:
Look at the network stack on each computer.....
Click to expand...

Not sure what you mean above. Is that (network stack) something
different from the output of `browstat status'?

Also .. you have asked for more information, so I'm posting some of the
requested information, but understand I have NOT done all you
suggested yet.

I have downloaded the XP support tools which include browstat.exe
Have you tried "\\hostIPaddress", as opposed to "\\hostname"?
Click to expand...

I think you've hit on something here... All but one host respond
nearly instantly. I'll be investigating that host after this post.

About the network:
I thought a diagram might not survive mail encoding so have posted a
network diagram here:
http://www.jtan.com/~reader/network/net.cgi

I'll also describe the network briefly here:

All lan addressing is static and done by hand all addresses are of the
format 192.168.0.X[X] all netmasks are 255.255.255.0 all are pointed
at the same gateway (A Netgear F318 router)

The network:

Internet => DSLmodem (gets IP by DHCP from Internet Provider) =>
Netgear F318 Router/Firewall get the Internet DHCP address and manual
Static lan IP =>

A Wireless Access Point is connected to netgear router feeding a
laptop with static IP. Mch1 is connected to Netgear router with
static IP, An uplink to a 1000/100/10 (gigabit) hub is connected to
Netgear router.

The Gigabit hub has 4 machines connected.
One runs Linux (samba) the other 3 run XP pro). Again all of these
have static (by hand) addresses of the above format and are pointed at
the Netgear gateway.

Ahh I see nitecruzer has resolved.... so getting busy.

You're getting slow DNS too. Is this a problem on all 3 computers? All 4 even?

What DNS servers do you use (IP addresses), and where are you located,
geographically?

No... wrong assumption. It was just your site. A temporary problem.

Site is Gary Indiana
servers are:

68.94.156.1
151.164.8.201

Those are assigned dynamically and belong to att.yahoo

Using your pages to get a Node Type assigned I find it fails
miserabley to edit the registry adding ...NetBT\Parameters\Node Type.

Or adding ...NetBT\Parameters\Enable Proxy

Neither of those addidtions gives me Node Type = broadcast. ipconfig
still reports `Node Type ... unknown'. But as you point out, It
should work like Node Type = broadcast anyway.

In previous post, following your suggestion, I reported that all but 1
host repond instantly if \\192.168.0.XX format is typed into `windows
explorer'. Below are reports on that computer and one of the fast
reponders.

The reports are the output of these commands:

ipconfig /all
browstat status
net config server
net config workstation

The slow host (listed first) is harvey.local.lan (192.168.0.22)

OK, no extra protocols - just NetBT and SMB Direct.

Why 5? What is Reader?

Have you tested both Chub and Harvey from each of the other 3 computers, and are
both consistent in results? Instead of comparing "\\Chub" and "\\192.168.0.1",
try comparing "ping Chub" and "ping 192.168.0.1", then "ping Harvey" and "ping
"192.168.0.22".

What's different between Chub and Harvey, that isn't different between Harvey
and the others?

Here are two possibly relevant registry settings for you to check:

Because only five machines were up during this test. The 6th is a
laptop connected by wifi as in the diagram.

Note: I have added full lan IP and smb names to the diagram posted
here:
http://www.jtan.com/~reader/network/net.cgi

Reader is a linux machine running samba (Linux tools that speak smb)
I had set it prior to testing to always win the preferred master
browser elections.
Have you tested both Chub and Harvey from each of the other 3
computers, and are both consistent in results?
Click to expand...

No, from anywhere but harvey, typing either \\IPnumber or \\IPname for
harvey sees a terribly slow response.
Instead of comparing "\\Chub" and "\\192.168.0.1", try comparing
"ping Chub" and "ping 192.168.0.1", then "ping Harvey" and "ping
"192.168.0.22".
Click to expand...

Pinging from anywhere to anywhere, using either numbers or names
appears to work the same on any machine.
What's different between Chub and Harvey, that isn't different
between Harvey and the others?
Click to expand...

I haven't actually seen anything different in any of them in test
results. I used chub as representative.

The thing that has come up different for harvey is what you directed
me toward:

I find with further experimentation:

(chub = 192,168.0.1
harvey = 192,168.0.22)

Typing \\192.168.0.1 or \\chub in windows explorer from
anywhere including harvey is near instantaneous.

Typing any other lan host (except harvey) likewise. But
Typing \\harvey or \\192,168.0.22 from anywhere (except harvey) is
terribly slow to resolve.

I cannot find what is different that might cause that.
Here are two possibly relevant registry settings for you to check:

http://nitecruzr.blogspot.com/2005/07/restrictanonymous-and-your-server.html
Click to expand...

Neither of these appear to be a problem on any of the machines.

A further question: In my case the lan names like chub.local.lan ( I
use `local.lan' as domain). are made up names. No nameserver anywhere
will be able to resolve them. With that in mind, how should I set
things at:

Mycomputer/properties/Computer name tab/change button/more button/

At `Primary DNS suffix of this computer'

Should anything go there? I have tried it with `local.lan' inserted
and left blank but saw no difference either way.

Would a cdiag report help you analyse this?

OK, no extra protocols - just NetBT and SMB Direct.

Both Chub and Harvey report:

Why 5? What is Reader?

Because only five machines were up during this test. The 6th is a
laptop connected by wifi as in the diagram.

Note: I have added full lan IP and smb names to the diagram posted
here:
http://www.jtan.com/~reader/network/net.cgi

Reader is a linux machine running samba (Linux tools that speak smb)
I had set it prior to testing to always win the preferred master
browser elections.
Have you tested both Chub and Harvey from each of the other 3
computers, and are both consistent in results?

No, from anywhere but harvey, typing either \\IPnumber or \\IPname for
harvey sees a terribly slow response.
Instead of comparing "\\Chub" and "\\192.168.0.1", try comparing
"ping Chub" and "ping 192.168.0.1", then "ping Harvey" and "ping
"192.168.0.22".

Pinging from anywhere to anywhere, using either numbers or names
appears to work the same on any machine.
What's different between Chub and Harvey, that isn't different
between Harvey and the others?

I haven't actually seen anything different in any of them in test
results. I used chub as representative.

The thing that has come up different for harvey is what you directed
me toward:

I find with further experimentation:

(chub = 192,168.0.1
harvey = 192,168.0.22)

Typing \\192.168.0.1 or \\chub in windows explorer from
anywhere including harvey is near instantaneous.

Typing any other lan host (except harvey) likewise. But
Typing \\harvey or \\192,168.0.22 from anywhere (except harvey) is
terribly slow to resolve.

I cannot find what is different that might cause that.
Here are two possibly relevant registry settings for you to check:

Neither of these appear to be a problem on any of the machines.

A further question: In my case the lan names like chub.local.lan ( I
use `local.lan' as domain). are made up names. No nameserver anywhere
will be able to resolve them. With that in mind, how should I set
things at:

Mycomputer/properties/Computer name tab/change button/more button/

At `Primary DNS suffix of this computer'

Should anything go there? I have tried it with `local.lan' inserted
and left blank but saw no difference either way.

CDiag is good for diagnosing complex relationships, and we might yet get to it.
If we do, we'll want to involve all Windows computers.

I think that we have a clue here though.

Compare the speed of "\\harvey" and "\\192.168.0.22", to "ping harvey" and "ping
192.168.0.22", from Chub, and from one other computer.

Glory be... on todays bootup I see snappy response to \\harvey
\\192,168.0.22 and pinging in both formats from 2 machines (not
harvey) appear to all show 0ms round trip.

All I knowingly changed was removing `local.lan' from:

Mycomputer\Computer Name tab\Change button\More button\
`Primary DNS suffix of this computer'

That box is now blank but formerly held `local.lan'

I may not have rebooted all computers following that change yesterday.
I meant to, but may have gotten distracted after the first 2 or so.
