CryptographicException: Object already exists

[alexdodo]

I have 10 computers in my network with vault client (Version=5.1.1.19215) (with windows 7 and win 2k8 R2).
Yesterday one computer with win 2k8 R2 stopped working
In the client log say:

Im follow the solution in the post http://support.sourcegear.com/viewtopic ... ion#p75376 but I can't fix the problem (in win 2k8 the folder %ALLUSERSPROFILE%\Application Data\Microsoft\Crypto\RSA\MachineKeys don't exists, the folder in win2k8 R2 is C:\Users\All Users\Microsoft\Crypto\RSA\MachineKeys, i think so).

I have 3 or 4 computers with the same wind2k8 R2 and don't have any problem (in windos 7 I have one computer with another error, I put a post with the description)

The server log don't show any message about this computer, but there are many error with the code:

Exception in plugin thread : The request failed with HTTP status 404: Not Found.

I don't know if this message is important

You have the path for the Machine Keys folder correct (C:\Users\All Users\Microsoft\Crypto\RSA\MachineKeys). The post I wrote was for Windows XP and Windows 2003 Server. Everything later uses the path you listed.

Give the account that Vault runs under read/write/modify rights to the MachineKeys folder.

Tks for your help.

In the vault client I put rights to everyone, and run the vault client like administrator, but I have the same error.

In the server side, the rights are ok (I think so). Vault server is used by 10 clients, so I don't want to move nothing from the configuration.

So, I put 3 images:
- The rights in the vault client computer (on directory C:\Users\All Users\Microsoft\Crypto\RSA\MachineKeys).
- The message error on the vault client computer
- The rights in the vault server (on directory C:\Users\All Users\Microsoft\Crypto\RSA\MachineKeys).

On the Vault server, what are the rights for Network Service?
