Hi,
I am setting up a network with my company. My company has 2 different offices, office A and B, which are not next to one another. They are about 50metres away. I have some contractors to lay out the lan cables. As I only want to connect the computers in these 2 offices together (not accessing internet), I used a Ethernet Switch and straight cables to connect up the computers. The ethernet switch is located in office A. My computer is also located in office A, together with 2 more other computers. As for office B, there are 4 computers.
After all these are setup, I tried to ping on all the computers. I found that my computer (in office A) is able to ping the other 2 computers in office A but cannot ping any in office B. The error I got is as shown below:
Pinging 172.100.100.15 with 32 bytes of data:

All the computers are running on Windows Vista. The model of the ethernet switch that I am using is Linksys SLM2008
These are the static IPs that I am using, with all subnet mask at 255.255.255.0:
Office A
My computer: 172.100.100.9
Computer 1: 172.100.100.2 (can ping)
Computer 2: 172.100.100.7 (can ping)
Office B (cannot ping any)
Computer 1: 172.100.100.13
Computer 2: 172.100.100.14
Computer 3: 172.100.100.15
Computer 4: 172.100.100.16
I suspect that it could be that the length of the lan cable is more than 100m. But I do not have any equipment to confirm this and to test the strength of the network.
Hope I did not miss out any required information. Could anyone tell me what could be the possible reasons and solutions for this?? It is okay to add in devices (like router if necessary) but I do not want to re-lay the lan cable.
Thank you & Regards
