So...here we go. I'm having an issue with one computer on a network not being able to ping other computers by name. I've spent the last day searching similar issues and I've tried all the steps recommended. If anyone has some suggestions, I'd love to give them a try - this is driving me nuts!!
I am connected via wired-LAN to a Linksys WRT-600N router; there are 4 other computers on the network. The other 3 computers are working perfectly - they can browse the network neighborhood and ping other computers by name.
The problem computer is set to the same workgroup and cannot browse My Network Places ("Workgroup is not accessible") and cannot ping the others by name. When I try, I receive "Ping request could not find host COMPUTER1. Please check the name and try again." It does not even attempt a ping. It can, however, ping by IP address. I can also ping internet sites by name and it correctly resolves to the IP address.
Here's some info, and steps that I've tried:
1. The TCP/IP settings are set exactly like the other computers (DHCP, default NETBIOS setting, and Enable LMHosts is checked).
2. The HOSTS file is present and contains only the typical single entry (as do the others)
3. I have tried "Enable NETBIOS over TCP/IP" with no luck
4. I have tried static settings with no luck
5. I have done a full virus scan and spyware scan and everything is clean. The computer also has no other "weird" issues.
That's all I can think of. Any help would be really appreciated. Thank you!
