Please note that you can cause damage to your system if you make a wrong move when editing the Windows Registry, so you do so at your own risk.

 The TTL value in the registry specifies the number of hops that a TCP/IP request can travel through before timing out. The default TTL is 32. If you ever have trouble connecting to a host that is more than 32 hops away, you can try increasing the TTL to 128.

Step 1: Open up the Windows Registry Editor. To do this click on the Windows Start button, click on "Run" and type in "regedit" before clicking "OK".

Step 2: Find the following registry key:

HKEY_LOCAL_MACHINE\ System\CurrentControlSet\Services\VxD\MSTCP

Step 3: Look for a string named "DefaultTTL". If you don't have this then you will have to create it (see screenshot):

Step 4: Once you have located or created "DefaultTTL", you need to set the value of this. Here you can set the value between 32 and 128.

Step 5: Close the registry editor and reboot your computer.
