Failed to connect to the network adapter. Peer is not accessible via VPN.

Returned to an older version, and now it works. Seems my problems are proportional to the power at Hamachi is raised. :)

[Bernardo Dias]

Steps:

1) Kill the process "hamachi-2.exe"

2) Disable and enable the hamachi network adapter
3) Start again the service "LogMeIn Hamachi 2.0 Tunneling engine" from the control panel
4) Start the Hamachi client from the Start menu

worked for me!

I didn't need to uninstall/reinstall Hamachi neither to rollback its version (current: 2.0.1).

I suppose there are some issue related to Vista hibernation.

Thank you Bernardo.

The steps above resolved the Hamachi "Failed to connect to the network adapter" issue. 

I too suspect hibernation to be involved.  FWIW, this was on Windows 7.

Thank very much man, your solution REALLY works! It helped me 'coz I also encountered this problem and didn't know what's up. So thanks again!

ar..i have the same problem and the solutions here dun work for me.

i tried to re-install with logs file now and this is what i get.

02 11:04:34.508 (nicmgr) Installing driver...
02 11:04:35.101 (nicmgr) Error while installing hamachi: SetupDiCallClassInstaller failed with code 000005aa

Steps described by Bernardo Dias didn't help on Vista 32 machine either.

If it related to hibernation, what are the steps to fix it?

Anyone has other suggestions?

[Watso]

If you don't mind I'll answer to my own question and all the others still waiting for the fix.

Had to gather all the messages from the two related threads and guess the way, step-by-step

1. Uinstall Hamachi Adapter from Device Manager
2. Uninstall Hamachi 2 (leave settings checkbox clean)
3. Reboot
4. See if Hamachi configuration folder is still there if not copy back the folder
5. Run the installer from website and it should detect your original settings and recreate adapter as well

Done!

Since I broke my neck and cried blood over this over a number of days, I thought I might save a few grey hairs out there. This applies mainly for Windows 7 clients:

1. uninstall Hamachi via the control panel as with any other application
2. Start "regedit" via the command line interface (type "cmd" in the search bar), search and destroy all hamachi references
3. Reboot
4. Run Hamachi installer directly from the web link on your account on the hamachi web site

Bernardo's solution fixed my problem. I had the yellow caution signs by every client. I am running XP Pro.

I might point out that where he says restart the LogMeIn service from the "Control Panel", this apparently is for another OS, as it is not in my Control Panel. So if you don't have it:



Click "Start"
Click "Run"
Type "services.msc"


Find it in your Windows services list.


P.S. It sure is a pain to edit posts in this forum :)
