[Shift General] deprotector:
Thaihugo, thank you again for your support. I will confirm here every step completed and this should help on finding the issue I have:

1. "first, know the name of your shift. If you didn't change it it is SHIFT, otherwise type hostname in a command line in vista side."

Done! My Windows 7 computer name was changed to: SHIFT

2. "then type services.msc and make sure the server service is started and set up to automatic if you want it to start every boot"

Done!

3. "Now type \\shift in your start menu. A windows must open, and you should see thinks, like Users,and printers. If not, don't worry, you can still go on. For more advanced users, it can be a good time to set up a share."

Done! I can see "Users" and "HTC Shift" folder. "HTC Shift" folder was created by me on partition D: (I have partition C: with Windows 7 only and D: for anything else) and set as shared folder with read/write/execute options for all users "Everyone".

4. "Now go on Snapvue side, and go to settings-connections-network plugin. First click on the "enable network folder" and wait for the reset."

Done!

5. "Now, when reset is done, start usbtools to activate activesync. On vista side, make sure you are connected ( set up a partnership, or just click on connect whitout partneship. In this case, you will have to do it each time.)"

Done! I choose "connect whitout partneship".

6. "Go back on Snapvue, and in network plugin click on New...

In remote path, enter \\shift\users if shift is your computername, and if you saw Users in the window on the second step. Otherwise, you can enter \\shift\c$ to access the whole drive. Click on map drive. Enter your username and your password (the one you use to login in vista)"

Done! I tried with \\shift\users and also with \\shift\htc shift or with \\shift\c$ and after some little time I get the same error "Map Drive failed".

7. "Make sure you have properly setup a share under Windows 7

Create a dedicated share, don't use the share wizard (in your explorer, go to options, and deselect the last one: use sharing wizard."

Done! I created "D:\HTC Shift" folder then right click on it Properties - Sharing - Advanced Sharing , I selected "Share this folder" then click on "Permissions" and I have "Group or user names" set for "Everyone" and at "Permissions for Everyone" I have "Full COntrol" , "Change" and "Read" all selected!

8. "Also, all your accounts must have passwords. specially administrators ones."

Done! I have only one Administrator account named "Admin" and have password.

9. "Create a share without any right (all users allowed, on share and on NTFS)

go to the file explorer on WM side. Select menu, then open path - new path

enter \\shift\yourshare

It should connect.

Done! but still don't have the connection...

10. "If not, go to the Windows 7 side, click on the start menu, and search for "local". You will have local policy settings. go to local policy, security settings, then network security: LAN manager authentication level. Select "send LM and NTLM responses". Confirm, reboot your pc and retry. It should work."

Done! but still don't have the connection...

Don't know where is the issue but there should be something else which made the difference between my configuration and yours...
