I've been trying to figure this out for a couple of days now and no luck so I thought I'd ask here.
We have two buildings connected via a line of sight wireless network bridge. We have two routers, one at each building and one, at the new building, is setup to be our gateway and the other, at the old building, is setup in "bridge" mode. Our internet is shared between both buildings via this bridge and all the computers on the network have internet access which means the bridge is functioning.
The problem is the Server, which is at the new building, cannot talk to the computers at the old building and they cannot talk to it. It was working fine Friday of last week. The computers at the new building can talk to the computers at the old building without any trouble.
Note: By talk I mean share and access files and folders.
The question is, why can't the server talk to the computers at the old building when the computers can talk between themselves just fine.
- The router at the new building is our DHCP and DNS.
- Everything is properly pointed to the router at the new building.
- I tried restarting the computers, server, routers, and network bridge and nothing fixed the issue.
- Our server is setup as a file server only, nothing fancy.
- There are about 30+ devices on the network, some wireless and some wired.
- The server is Windows Server 2008 r2
- The computers are Windows 7, XP, and a couple 8.1s.
- I also cannot ping the computers at the old building from the server. However, I can ping any computer at the old building from any other computer at the new building.
If you need more information please let me know. I'd really like to get this problem solved.
- The server has a static IP address
- All computers are on the same subnet
- There is a firewall, but I tried disabling it and nothing changed.
- When attempting to access the server by Hostname or IP address, i.e. \\servername or \\192.168.1.111, we get a "Network Path Not Found" error.
- The server has an Avast Firewall installed in addition to the built in windows firewall. The windows firewall is disabled while Avast's is enabled.
- I have not tried adding the server to the DMZ on the router for security reasons. I may try this later though.
- There are no static routes configured on either router, I did just configure a static route on the new router for the server to see if it fixes the problem.
- We do not use group policy, the company was using Windows Home OSes until I was hired and started getting everything switched over to Windows Professional. As such, the server was configured as only a File Server with no Active Directory/Domain anything.
- I have not tried messing with the HOSTS file but might when I get a chance.
- We do not use VLANs of any sort, we just don't for no reason in particular.
- I've checked all the IP Addresses, Subnets, LAN Adapters, Network Teams, Routes.
Tracert Results (Note: IP Addresses listed are not the actual IP Addresses)
- Server to Old Building: "Server [192.168.1.111] Reports: Destination Host Unreachable."
- New Building to Server: "1 1 ms <1 ms Server [ab12::cd34::ef56::gh78::ij90]"
- New Building to Old Building: "1 3 ms 1 ms 1 ms ComputerName [192.168.1.111]"
- Old Building to Server: Will post when I get a chance to run the test.
