Network connection problem on 2003 Domain

Hello experts,

I have a unique problem I could use your help with.  We have several Dell Latitude D505 notebooks we use on our network.  Since the last round of Windows Updates, on Tuesday May 5th, (we push them out to all workstations) these laptops will not connect to the domain.  All other workstations will connect just fine.  We're pretty sure it's linked to the updates since some of the notebooks worked all day *until* they downloaded and installed the udpates.  If you look under My Network Places, under the LAN connection, it shows "Connected", but is only sending a few packets, nothing is being received.  I asked our consultant to check out the switch and the MAC isn't showing on the switch itself which leads me to believe it's a problem on the notebook somewhere.  Pings to itself yield a reply, but it can't see anything else.  We've tried the obvious stuff like updating the NIC driver, ran a Windows repair, ran a repair on the Winsock and even went so far as to reformat and reinstall Windows XP.  I don't see anything unusual in the Event Viewer, but could be overlooking something.  I'm a loss and would really appreciate any insight...  

Here's some pertinent scoop:

Notebook:
Windows XP Pro, SP2
Intell Pro/100 VE Network Connection Card
Plugged into a Cisco 2960 switch
Trying to attach to a Windows 2003 AD Domain

Hi

Goto command prompt -> and give nslookup google.com

Does that return an IP.

also does ipconfig return an address on your subnet

Are you able to ping the gateway?

Can you do a tracert <your AD IP> and see where the packet is dropped.

regards

Hello Dinesh,

nslookup gives me a "DNS request timed out" message, so no IP was returned.
IPconfig displays the IP address of my machine (we don't use DHCP so all IPs are hardcoded onto the machines.  It's a limitation of the proprietary hospital software we use).
No reply from a ping to the gateway IP
A tracert to the AD just gives me a bunch of timeouts.  

Thanks for the suggestions, though.

Hi,

Can you try to plug in the laptop to a different network port - lets say on another floor.
Also can you disable the windows firewall and chk.

regards

Sorry, I should have already mentioned.  The notebook has been tried in 4 different switch ports on multiple switches in the IT closet.  Also, the Windows firewall has been turned off.  

Thanks, though.

Have you guys tried to "Rollback Driver"?  

Also, what you note what KB# were installed if rollback didn't work?

I didn't think of doing that but will try it...

I went to the Device Manager and did the Rollback Driver.  It never gave me an error, but then again, I couldn't tell any difference.  The date of the driver remained the same.  The updates that were installed on 05/05/09 were these:
KB959426
KB956572
KB960715
KB952004
KB961373
KB963027
KB967715
KB955839
KB923561
KB960803

Also, don't know if this helps, but my server had problems installing the MS .NET Framework 3.5 SP1 udpates.  When I look on this notebook, I see that update listed there, but there's no "Installed on" next to it.  Do you think a mismatch of this type of update could cause these problems?  Like it's installed on the server, but not on a workstation?  I'm not really sure what the .NET framework does and if it has anything to do with the problem I'm seeing here.  It's definitely something unique to these notebooks...or the NICs in them.

.NET Framework 3.5 should not been causing your network issues.  Frameworks are the programmatic environments developers use to write apps.  3.5 Framework is the latest and is used in Visual Studio 2008.

Most the updates you listed are security updates for remote attacks.  This is okay.  I was looking for auto updates to a piece of hardware.

After re-reading your initial question, you mentioned you have reinstalled the operating system and you are still getting network issues.  Is that statement correct?  

Another question:  You say the notebooks are connecting, but don't work.  Can you tell me the speed and duplex they are connecting at?  Also, can you post an ipconfig /all of a notebook?

Thanks.

I didn't see any particular hardware updates that were installed on the 5th.  It feels like it must be something unique to this notebook since all 6 of them are not working and all other workstations are.  And yes, we did a reinstall of Windows on one of the notebooks, thinking that would remove any question about the Windows updates.  

I should have been a little more specific about the "connecting".  Under My Network Places, View Connections, the LAN connection is showing "Connected".   If I double click on the icon, I see the Packets Sent/Received.  It's here that I can see there are some that are sent, but none recieved.  If I look at the Intel PROset utility, I can see that there are 120 packets sent and 13 receive errors.  Unfortunately, it doesn't tell me any more info than that.  I'll get an ipconfig /all attached... The Primary DNS Suffix is blank because I can't get the machine to connect to our domain.

Thanks,

j

According to your ipconfig, you are using static connections.  Have you tried changing your static settings to dynamic?  And are your workstations setup with static as well?

Sidenote:  Your Catalyst 2960 ports designated for these notebooks are all on Auto Negotiate, right?  I'm trying to establish that your net admins didn't change it to 1000 Full for a Network card that only can handle 100 Full.

We don't use DHCP due to a limitation of proprietary hospital software.  So, all our workstations use statically defined IP addresses.  I double checked and the Cisco switchports are set to auto negotiate so we should be OK there.  Do you think we should hard code this port to 100/full? FYI, I've tried both the original NIC driver that came with the laptops (6.4.14.81 dated 8/21/2003) and a newer one (8.0.47.0 dated 12/6/2007)

Thanks for all the help...

You can try dynamic IP and connecting the laptop to  any router that has dhcp enabled and see if you get an IP address and if you can connect to the internet. You can also point your DNS to the gateway and see if you can access the internet.

OK...I'll give that a try.  I'll post back when I have some info.

I would go ahead a try on both the switch and the notebook changing it to 100/Full and see what happens.  

I would also tell you to check "Local Area Connection" properties.  Recently we had a user's laptop install a protocol that was meant for small networks.  We disabled it and the NIC started responding the network.

I've attached my notebook's LAN properties as a reference.

Let me know if the switch modification worked.

Thanks again for the suggestions.  We went ahead and tried an old USB NIC (Belkin) that we use with an older laptop and it connected to the network right away.  So, I'm convinced it's something to do with the Intel cards.  Does anyone know of a problem with these particular cards?  It's an Intel PRO/100 VE.  I've tried 2 different drivers, but maybe haven't hit on the right one yet.  I'm also wondering if the BIOS got updated somehow and that's messing with the Intel card.  

Flopez235, I did go ahead and set the switchport and the laptop to 100/Full with the Intel card and it didn't help any.

Thanks,

I would still try and point the DNS to the gateway and once it says connected try pinging 4.2.2.2

 I tried pointing the DNS to the gateway and pinging 4.2.2.2 and get no reply (it timed out).  What does that do, anyway?  (Just curious)

And it won't let us do a system restore...

Thanks for the suggestions.

The gateway usually has its own DNS. as for the IP address 4.2.2.2 is a dns server, If you can ping that then you can point the alternate DNS to this IP  and you would be able to access the internet.

The Bios doesn't update by itself, The thing I don't understand is once you reinstalled windows why this still doesn't work.
Does the computer you reinstalled windows have the same computer name and IP address you had prior to reinstalling?

Thanks for the explanation on the 4.2.2.2 address.  Yes, we were using the exact same IP address and computer name.  Another thing we did was to take the Cisco switches and AD out of the picture.  I made a teeny little network of two of these non-functioning laptops and connected them with a little switch.  Still unable to receive anything.  Both would send packets.  

I'm really baffled by this.  We feel like we've narrowed down the problem to the Intel Pro/100 VE NICs in the Latitudes, but have no idea what happened or why.

Thanks for the suggestions, though.

Hello Experts,

We ended up just buying a $20 PCMCIA NIC for the laptop.  I still don't know what happened, but it was more cost effective to just cave in and get the cards.  Thanks for all the suggestions.  I'm not sure what to do with the points, though, since none of the suggestions fixed the problem.
