You know that to be able communicating via the Internet, computers use TCP / IP protocol.
In simplified terms, we can say that the TCP / IP protocol "cutting" all informations (Web pages, emails, downloaded files ect ...) into "data packets". Then it adds a destination address and delivers these packets at the right place.

The TTL (Time To Live)
The TTL is the maximum number of addresses in which can pass to reach its destination. Contrary to what its name suggests, the TTL is not the "life duration" of these packets.
By default, this number is limited to 32 addresses, this may be insufficient in some cases. Imagine that the site you want to view requires going through 33 addresses!
A message appears, saying that it is impossible to find the site, although there is a strong chance that the site really exists.
You must therefore increase the TTL, that you'll define to 64 for a modem connexion and to 128 for cable or ADSL.
To do this, edit the registry, then open the following key:
(See Fig 1 to 9)
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Servic es\Tcpip\Parameters
Create a new DWORD value, that you will name DefaultTTL
Give it value 64 or 128 (see above).
Important Note: Select the the decimal base!
Then validate with OK.
Close the Registry Editor, and restart Windows...
