VMWare troubles

I’m having a problem with Comodo and VMWare. Basically the localhost can’t connect to a server inside a virtual machine, but all the pc’s in the network (wireless) can. When pinging, the VM responds for 1 or 2 seconds then it stops responding for another 1 or 2 seconds. The VM can connect to the network, I can navigate and update the server perfectly, the only thing that I’m unable to do is to connect from the localhost to the VM. Any ideas?
