So i have always wondered what causes this so i will see if any of you can help.

I have computers on a network, all computers work fine, able to access network recourses and the internet.
But, from my PC i am not able to ping a certain computer. Out of about 200 computers there will be around 20 that i cannot ping. Operating systems ranging from Xp to Windows 7.

Firewalls are all turned off. Computers are on the same domain with the same IP address range. Pinging both the IP address and Domain name yields the same result.

Does anyone have any ideas what i could try next?

What antivirus you using on the PC's you can't ping?

With some AV's you need to trust the network card or they have a firewall.

Trend Micro.
Will turn off the AV firewall and test quick.

EDIT: Nope, still no luck. Turned off the AV altogether.

Is the PC you testing from a Win 7 pc?

If so you need to go to advance option under firewall and fully turn the firewall off on all three tabs "domain" "private" "public"

My PC is windows 7, all 3 firewall options are off.
Client PC is XP.

I cannot ping the hostname of IP address.

Might be the case, though he says the firewall is turned off completely...
I have had instances however, where apps would not connect while firewall was disabled, but only when firewall enabled with exceptions for those apps... or ports.

When in doubt I disable it and kill any related processes or simply uninstall it to be sure. You never know what these apps are doing.
 
I've had similar problems and the fix was to uninstall and reinstall or upgrade the network card driver

hope it helps

Does this mean you cant ping the hostname but can ping the IP ?
If it is the case try to ping it from another PC on the hostname if it can then it could be that there are DNS problems

Try to clean your PC's dns cache by running ipconfig /flushdns from the cmd prompt
do this on both your PC and the other PC if it doesnt solve the problem.

are you on a MS domain ?, try to delete the computer from DHCP in administrative tools on the Windows Server if you are. then relese and renew the IP lease.

ipconfig /release and then ipconfig /renew
 
What is your IP/subnet and an example computers IP/subnet? Rather check it and be sure...I may well be barking up the wrong tree here but if yours (a) is 192.168.1.25/255.255.0.0 and the other (b) 192.168.2.26/255.255.255.0, you will in theory can get to it (b) but it does not know how to get back to you (a) because it is actually on a different subnet...if I am making any sense?
