  After the upgrade yesterday from Vista to Windows 7, now my Cisco VPN does not work and I get an error message titled: grounds 440 driver fault.  Any ideas to fix this?

  This was the solution!  The works of vpn as $ 1 million now.  I followed the instructions above to enter the uninstall program and selecting the repair option.  I rebooted the machine, then used the troubleshooting on vpn software compatibility option.  Selected Windows windows xp (service pack 2) as the correct software and cisco vpn client started right up.

  Thanks, Nick!

  Your signature says you're running snow leopard 10.6.4. If this is the case you must update to 10.6.8 in order to get the Mac App Store:

  Mac OS X 10.6.8 Combo Update v1.1

  You will need to upgrade to El Capitan until you can upgrade to Sierra:

• Firefox shows "the peer certificate has an invalid signature." ISMA shows "could not trust this certificate for unknown reasons.

  With the help of a PKI on site of 2 levels. Root CA offline (Standalone Windows 2008 R2, Enterprise Edition) and Isma online for delivery of certificates (Domain-Joined, issuing CA)

  ROOTCA certificate installed in the store and the approved display (PKCS #1 SHA-256 with RSA algorithm encryption and uses a signature SHA2)

  ISSUINGCA certificate installed in the store and display "couldn't trust for unknown reasons" has also SHA2 signature with the RSASSA-PSS algorithm

  Certificate issued is for a Web Server front end Lync and when it tries to load the secure web connection. I get the message "the peer certificate has an invalid signature."

  I completely uninstalled and reinstalled Firefox. Removed and added certificates ROOT and ISMA. Note: No problem when using the same certificates in Internet Explorer 8, 9 or 10 on the same system. Lync client also uses the same certificates, no problem. Only when access to the Web Services of Lync from Firefox.
  Question: Firefox NSS #11 internal Module PCKS supports RSASSA - PSS SHA-256 with different hashes? How can I solve this further?

  I finally found the problem. The ROOT CA has the following registry key configuration when cert Isma was published:

  HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\CertSvc\Configuration\IssuingCA\CSP\AlternateSignatureAlgorithm = 1

  This CA cause ROOT to issue the cert with a signature that is encrypted with the algorithm RSASSA-PSS (1.2.840.113549.1.1.10).

  This signature replacement algorithm no is apparently not supported for use with Firefox 27.0

  I changed the registry value on the ROOT CA to a value of 0. Renewed the cert IssuingCA (using the same private key) which is now on display with sha256RSA encryption. I have republished all my default web certificates now using this new broadcast chain CA without problem.

• Message saying that the Generic Host Process for Win32 Services has had a problem and will end. Then I have no sound more until I reboot

  I have a hp Pavilion working with XP but recently I installed Windows Office 2007. Since then, I have problems with the sound system. I got a message saying that the Generic Host Process for Win32 Services has had a problem and will end. Then I have no more sound. I can't open the volume control as the system says that nothing is installed. I always need to restart my computer to get the sound working again. Help!

  Thank you, Jerry. I'll try it, but for now it works well. I fit it and it seems to have done the trick.

  See you soon,.
