I am trying to troubleshoot what is seeming to be a networking issue.
The network that I am working with has 4 computers going through a linksys wireless router, some wireless, some hard wired. The problem computer seems to be denying all inbound connection and we cannot figure out why.
This computer has internet access (in fact, I'm making this post from it) just fine and it can ping every other computer on the network (192.168.1.101, 192.168.1.102, and 192.168.1.103) , but none of the other computers can ping this computer; nor can the computer ping itself (192.168.1.104 - Request Timed Out).
It can ping localhost just fine (127.0.0.1).
Currently, there is no form of antivirus or firewall running on the problem computer, or any of the computers that are trying to access it. This particular computer is connected wirelessly, but we have also tried connecting it directly to the router for diagnostic purposes, but still to no avail.
This problem started when we updated the our business software. Every computer was updated, but this is the only computer that is giving us any issues. Any help would be appreciated!
