this is the problem on the laptop
DHCP Enabled. . . . . . . . . . . : No

Setup to Automatically get an IP and DNS (DHCP) - for Vista
http://windows.microsoft.com/en-US/w...CP-IP-settings

although that fixed IP should have worked - BUT depends on how dhcp is set up and if another device also is using that IP 0 in which there would be a conflict message

change to auto and see if it connects

ReStart (reboot) the machine.

If you receive the message
The requested operation requires elevation.
Then please open the command prompt as administrator - as requested above
Start> Programs> Accessories> and right click on Command Prompt, select "Run as Administrator" to open a command prompt box

Ok, heres the report from the cmd.prompt:
Microsoft Windows [Version 6.0.6002]
Copyright (c) 2006 Microsoft Corporation. All rights reserved.

C:\Users\Christopher>netsh winsock reset catalog

Sucessfully reset the Winsock Catalog.
You must restart the computer in order to complete the reset.


C:\Users\Christopher>netsh int ipv6 reset reset.log
Reseting Echo Request, failed.
Access is denied.

There's no user specified settings to be reset.


C:\Users\Christopher>

Obviously I didnt restart after the first reset, so I do not know if that caused the error message in the second one?

EDIT

Is the laptop we need to get working - the desktop is OK

so ignore desktop for now - only tests should be for the laptop
so firewall on laptop - Norton, trial - whats the make and model of the laptop
Quote:
Access is denied.
That maybe the issue - reboot and try again - make sure you "run as administrator"
usually you get that error on both ipv4 and 6

try- safemode with networking
as the PC starts keep tapping F8 - a menu appears - choose
safemode with networking - see if that works

The only way I have seen access denied resolved - is to uninstall the adapter
goto device manager
click on the + for network adapters
right click on the etherent adapter
and remove/uninstall

reboot/restart the PC
and allow windows to detect new hardware and to re-install the drivers again

Ok, have tried all of the above and keep getting that same error message, no user specified settings to be reset.

Tried it in safe mode, uninstalled the adapter and did it after the other reset restart - no joy.

Oh yes, sorry forgot.

Okay, no third party firewall, now, although YEARS ago I did put one on but cannot recall what or who it was from.

I uninstalled Norton trial right at the beginning when I bought this laptop and have run Avast ever since, and at one stage I had NOD 32 also running on it but got rid of NOD about three years ago.

Laptop is an HP Pavillion with Vista Home Premium.

these programs from years ago, can still interfere with the laptop - had a few like this on the forum, one of norton from 2007 - suddenly blocked all access
HP usually supply Norton as a trial - so remove that with the removal tool

lets just try removing those old programs - certainly run the norton removal tool and the Nod 32 - see below

- and also need to see the service status from the laptop - incase dhcp client is not running - see all below
Quote:

I have added AVG , mcafee and Kaspersky as they are popular security suites - and most have caused this type of issue

------------------------------------------------------------------------
Status of Services

We would like to see some status information for each of the services listed below.

To do this goto

Start> Run {search bar in Vista/W7}> type CMD to open a command prompt box (A new dialogue box - black with white font, will appear on screen ):

Type the following command
SERVICES.MSC

OR
Control Panel>
Administrative Tools>
Services>

then for each of the services listed below - Please post back the following status information;
If the service is set to Started or Stopped
and
If the service is set to Automatic or Manual
  • COM+ Event System (for WZC issues)
  • Computer Browser
  • DHCP Client
  • DNS Client
  • Network Connections
  • Network Location Awareness
  • Remote Procedure Call (RPC)
  • Server
  • TCP/IP Netbios helper
  • Wireless Zero Configuration (XP wireless configurations only)
  • WLAN AutoConfig (Windows 7 & Vista wireless configurations only)
  • Workstation


If any of those services are not started/running,
then right click on the service
then from the menu choose properties and now check the dependencies.

for each dependancy entry - Check each of one of the dependencies and see which one is preventing the service from running/starting.

I would recommend that you restart the PC and run the removal tool for a second time - I have found instances where the removal tool needs to be run twice to fully remove all traces of norton and symantec from the PC

Ok, shall double check the services but I did just now and they were all running.

A query I have is why did my laptop yesterday work fine here at the office, but today when the tower is plugged into the network then decide to drop its connectivity?

Let me get these things done and get back to you.

Thanks again.

dont know , didnt know it was working OK in the office yesterday

check the cable is OK and plugged in at both ends
try using the one the desktop is plugged in to
- do a power cycle

restore the laptop to the day before yesterday
------------------------------------------------------------------------

How to power cycle

“power cycle” process to reboot or reset the modem/router
  • Switch off all the devices modem, router and computers also unplug their power cables.
  • Wait at least 1 to 5 minutes,
  • Plug the power cords back in, but don’t switch them on.
  • First turn on the modem and then wait for a few minutes for it to settle and all the lights to become stable.
  • Next switch on the router (if a seperate device) and then wait for a few minutes for it to settle and all the lights to become stable.
  • Now turn on your computer, You should now be able to access the Internet.
------------------------------------------------------------------------
------------------------------------------------------------------------

Restore PC to an Earlier Date & Time

Go Start>>All Programs>>Accessories>>System Tools>>System Restore
  • Click in the radio button Choose a different restore point
  • Click Next
  • put a tick in Show more restore points
  • Pick a Date before this happened
  • Click Next
This should restore the PC to that time & date

Hi Wayne, my one secretary just reminded me that our offices got hit by lightning at the start of the year back in January, and that got me to wondering. Anyway, one of the other laptops had to use a USB ethernet hub goody for accessing the internet. Anyway, plugged that into my laptop and hey presto, can see the network on both tower and laptop and can access my shared folders etc between the two.

I assume therefore that the laptops NIC is on the way out and its tie for a new laptop?

Also, have not tested whether the cable to cable connection works yet, but shall give that a bash.

Could that also explain the intermittent ability to see each other?

Many many thanks Wayne. I realise that I may have just wasted a ton of your time on this. BOM when you are next in sunny RSA.
