New Post: Failed to sign package; error was 2148081670

Heya,

after a successful migration from Server 2003 R2 to Server 2008 R2 with WSUS I wasn't able to sign packages anymore and got error number 2148081670 with WPP and LUP!

On the new WSUS server I just checked if the certificate is in the correct places and not if the private key is present.

Went to the old server, exported the WSUS cert with the private key, deleted the one without the private key on the new server, imported the cert with private key, went to WPP and voila, I'm able to sign packages again. :)
