Cannot Connect using computer name only IP address

Hi,

I successfully installed Hamachi, I can browse the gateway PC.

When I connect using the explorer bar or run, i can only use the IP Address to be able to browse.

But I can't use the computer name.

Example:

CANNOT CONNECT

\\sampleonly 

CAN CONNECT

\\10.152.8.9

The reason why I need to use the name because my access database is linked to the name not to IP Address.

Please advise.
