In my home network I have a desktop (ubuntu 12.04 - as a server), laptop (Windows 7 Ultimate x86 for work) and android phone. Since I installed samba3.6.3 with apt-get and configured shares only
I can't resolve correctly the server from my laptop using a domain I bought and configured, no matter the network it's in. I tried the office, some internet cafes and pub networks - it always fails to connect to any service. The problem is only with the laptop. Other computers from any network resolve it correctly and get service they require (ftp, ssh, httpd).
I tried flushing dns cache with
ipconfig /flushdns and it emptied the output
ipconfig /displaydns with no success.
Tracert does only one hop. Tracing the domain I bought leads directly to the public IP of the server and tracing the local domain leads to the local ip address of the server.
I have zero ideas how this happened. Any suggestions are appreciated, thanks.
