Hi Everybody,
Hopefully this is the right section for my question.
On a Windows 2008 server, we have a replica WSUS installed. An update is not being installed as the certificate verification fails. When manually downloading this file, I see that the certificate, used to sign the executable is not valid anymore (which is correct, however the signed date is within the valid period).
When I check the file on my Windows 8.1 computer, it does see everything as being valid.
It is invalid on Server 2008 / 2008 R2 / Windows 7
It is valid on Windows 8.1 with and without Internet connectivity.
I tried the following on the WSUS server (which does not have an internet connection):
Install all the CRL's of the certificates in the chain
Install the authroot stl file from Microsoft
Installed the rootsupd.exe from Microsoft
Nothing (other than changing the system date 2 years back) works.
Why is this working on Windows 8.1 and not 2008? What was changed in this particular case? I hope somebody knows, and that it is possible to implement/change this on Windows prior to 8.1
Thanks in advance.
