Although a long-shot, perhaps when the same name, there was also an IP conflict. Release and renew of the IP address might solve the problem. Personally, I'd recommend a DNS flush as well. The following will release/renew the IP address as well as flush your DNS cache and restore the HOSTS file:
Please copy/paste the lines in bold below to Notepad: @Echo on
attrib -h -s -r hosts
echo 127.0.0.1 localhost>HOSTS
attrib +r +h +s hosts
netsh winsock reset all
netsh int ip reset all
shutdown -r -t 1
Save as flush.bat to your desktop.
Right-click flush.bat and select "Run as Administrator". Your computer will reboot.
