Windows XP Professional SP2 (basically a new distribution). I cannot ping (or, obviously, access) a specific address on my network from a specific computer. The IP address is for a printer. This printer can be accessed by all other computers on the local network. The computer in question can be pinged from other computers. It can ping other computers. What I have tried:
The XP firewall is off.
The NIC is part of the Motherboard.
I have updated the NIC driver.
I have turned the NIC off (and on, later) in the BIOS (though this doesn't seem to stop it from working...?).
I have un-installed the NIC (driver), rebooted, then it is back (as I would expect).
The printer IP address is not in the routing table.
I reinstalled the TCP/IP stack.
I checked Winsock (using Microsoft utilities).
TCP/IP filtering is not checked (Advanced properties of Local Area Connection) - not that this is applicable.
I've checked various keys in the registry in the vicinity of HKLM\SYSTEM\CurrnetControlSet\Control\Print\Monitors\
I've checked the various tabs using the right-click of Printers window in the Control Panel.
The computer's IP address is assigned using DHCP.
>>> If I assign a static address to this computer, I can ping the printer. <<<
I have 2 new (refurbished) computers that are identical. When I first noticed the problem I was attempting to install the printer driver in computer A. I started up computer B, and could ping the printer. I swapped hard drives, booted Computer A with Computer B's disk. Couldn't ping the printer. Tried Computer B with Computer A's hard drive. Couldn't ping the printer. Put the disks back in the original computers and can't ping the printer from either computer. So now both computers can't ping the printer (unless I assign a static IP address).
It would appear that something has caused a hardware (firmware) type of change in the NIC. After un-installing the NIC, both driver and BIOS, I turned the computer off, unplugged the power - even overnight (as power continues to the NIC even when the computer is off). No change in behavior. I have not been able to find a way to "reset" the NIC.
I hope I have included everything I tried (but probably forgot something). And, yes, I have checked and rechecked the Windows firewall - it is off, however using the Static IP address proves that.
Of course I can use a static IP address for this computer, but I'd rather not.
Thanks for any ideas (probably obscure, at this point).
