A tech working for me put a new mobo in one of my work computers. At first, I didn't realize anything was wrong as everything seemed to work, it connected to the DSL modem and was on the internet (as I am on this computer now), etc.
This computer is what customer computers use to get updates, downloads, etc. when in for repair. When I was working on a customer's computer, I realized it wasn't connecting, so I tried to ping the host (this computer) and it timed out. Of course, I was troubleshooting the problem in the wrong computer especially when I realized each subsequent computer had the same problem pinging the computer in question.
I found my computer could not ping any computer on the LAN, localhost, its own IP. I resolved this problem by uninstalling Norton Personal Firewall 2003. Pinging by localhost 127.0.0.1 or 192.168.0.1 all worked again. BUT!!! I still cannot ping other workstations on the LAN, BUT, they can all ping each other.
First: Yes, I've tried different NIC's, new cables, uninstalled Client for Microsoft Networking and reinstalled, checked the registry for startup items. Reinstalled Service Pack 3 too.
Second: I *can* ping over the internet; tracert; etc. All my internet programs work fine (pcAnywhere, email, browsers of any brand, FTP, etc. etc.).
Third: I did re-install Norton Per. Firewall; that didn't help. I uninstalled it again; that didn't help.
Fourth: I checked my services; doesn't appear to be anything new or out of the ordinary.
Fifth: I can "explore" my workgroup AND all computers on my LAN appear, but if you double-click or try to explore them, you get an error:
\\<computer name> is not accessable
The network path was not found.
If a new computer goes online this LAN, it will show up too
Sixth: If you try to ping this computer by computer name, it will show the proper and current IP address. Example:
Pinging seabreeze [192.168.0.1] with 32 bytes of data:
Request timed out
I'm glad I can access the internet at least. I really need to get this computer back on my network though as it has utils and files I use daily, plus it is the internet proxy server. I am using ICS for sharing, not 3rd party software.
OK guys; what have I missed???
thanks in advance!
