This has been driving me nuts.
Our company has around 300 computers on our domain.
We just got in a new batch of Dell computers for new employees.
I have set up the new computers on the domain and they are receiving ip addresses from our DHCP server.
When I try to ping the new computers from my desk, the ping times out.
After further research into this, I found that its not just the new computers that I can not ping. Of around half of the pre-existing computers that were already on the network, I cant ping them either. Crazy thing is though, I can view EVERY computer from "My Network Places->Entire Network->Microsoft Windows Network->MyDomain". I can see all the computers in the network there. The ones I can ping, and the ones I can't ping. When I try to browse the ones I can ping, I can see their scheduled tasks and printers and faxes just fine. But when I attempt to browse one of the computers that I can not ping, I get the error:
"\\COMPUTER is not accessible. You might not have permission to use this network resource. Contact the administrator of this server to find out if you have access permissions.
The network path was not found."
All of the machines (can ping or not) can connect to their network drives and can browse the Internet. They (can not be pinged) just aren't allowing me to ping them or access them via "My Network Places->Entire Network->Microsoft Windows Network->MyDomain".
Any help is greatly appreciated.
P.S. I can ping the computer name and it gets resolved to an IP, but it still gets 100% loss.
