Ping(ing) Problem

[danrhodes]

Morning all this may be a long one!

 

I have a very strange problem at hand! I have a Fujitsu Amilo Pro V3515 Laptop, standard parts no addin cards etc.

 

This laptop connects to my wireless network through a HP 420 WAP, we have these setup all around school, everybody else can connect fine.

 

On our network we have a number of servers, all have static IP's and all are Fujitsu Kit, we use HP switches throughout.

 

When a user tries to logon to the network using this laptop they can successfully logon as our DC's are server3 and server4, no problem's yet.

 

When the user has logged on they do not get presented with the regualar desktop or start menu, the reason for this is because our shared start menu and desktop for both staff and students is stored on server5.

 

Ok here comes the problem........

 

I cannot ping server5 from the laptop, nor can server 5 ping the laptop back.

 

I have tried uninstalling an re-installing the hardware and the drivers. I have tried removing the wireless card from the laptop and re-seating it, in the hope that this may help, it didn't.

 

I can however, after setting a static IP on the laptop, ping the server for 3/4 pings on average. But even so the server still cannot ping the laptop back.

 

I can connect to the same router with another laptop and ping any server I like, even server 5, so its not a router problem.

 

The weird thing is, I can ping any other machine on our network from the offending laptop, just not our server5.

 

The laptop and the server are on the same subnet, the IP range is correct etc.

 

Anybody any ideas?

Check for viruses, IIRC conficker does some weird stuff like this and also you might want to double check firewall settings to make sure you have allowed file and printer sharing, ICMP etc...

 

HTH,

Hi,

 

Checked all that stuff, our firewall rules are setup by default by GP.

Compare ipconfig /all with a known working device.

How to reset Internet Protocol (TCP/IP)

 

Reinstall TCP/IP on Windows XP

 

Repair/Reset Winsock settings

 

I would reset tcp/ip completely - which will require a reboot and then install latest network card drivers / chipset etc

 

try again

Check DNS for duplicate/stale records?

[danrhodes]

In the end a restart of the server solved this problem?!

Typical IT Crowd - have you tried an unexpected forced reboot aka have you turned it off and on

Yea, "Initiating unexpected forced power cycle reboot!" Aka pull the plug!

or as I like to say "Operation pull the plug"
