I'm hoping someone can help me with this issue.
I have a small network in an office. I can connect to the internet via supplied router from both computers. I can communicate (Map a drive / Ping) from System A to System B but cannot communicate (map drive/ping/etc...) from System B to system A.
I can use external apps such as Teamviewer over the internet to see both machines so I'm positive this is an internal network issue with 1 of the systems.
The systems are connected to the network through the phones. Then the phones plug into ports on the back of the Cisco router.
I have the model number for the router but forgot to bring the paper with me today.
The IP address are issued via DHCP and there are DNS settings for the default and secondary gateways. Removing the gateway settings still enable me to connect to the internet with no problem.
I'm thinking this is a routing issue but would like some other options as to how I can troubleshoot this problem.
These are WinXP systems. What other info can I supply to help with the troubleshooting?
Thanks for the help.
