Hi
Have been running WHS-2011 since 2011 and after recent windows updates, all 5 of our home computers show up as offline and we can't access any backups.
No new computers show up either.
I have uninstalled the connectors and removed the machines from dashboard and when I went to install the connector there was trust issues, which I overcame by importing a certificate from the server. That got the connector installed but no connections.
On the server, in a log file named SharedServiceHost-AlertServiceConfig.2.log I see many entries with:
ProviderFramework: Information: [0] : PfErrorHandler: IGNORING WCF internal exception: (SecurityNegotiationException) The remote certificate is invalid according to the validation procedure. ==> (AuthenticationException) The remote certificate is invalid according to the validation procedure.
ChainTrustCertValidator: Certificate is not supported (not rooted from service's root cert). Expected root ca thumb=[8A5ACC7CDA0305C6D6FF7E562648990D1B396DA8], Actual = [4AE72E0721BD0831DA2D96BB7ADC03FD8E75B673]
Looking on the server at \Console Root\Certificates (Local Computer)\Personal Certificates I see 2x certificates with the server name followed by -CA
Issued to WHS-CA, Issued by WHS-CA, Expiration date 7/03/2052
Issued to WHS-CA, Issued by WHS-CA, Expiration date 25/05/2060
Details for the one with Expiration date 7/03/2052 has thumbrint of 8a 5a cc 7c da 03 05 c6 d6 ff 7e 56 26 48 99 0d 1b 39 6d a8
Details for the one with Expiration date 25/05/2060 has thumbrint of 4a e7 2e 07 21 bd 08 31 da 2d 96 bb 7a dc 03 fd 8e 75 b6 73
The 2 also appear in \Console Root\Certificates (Local Computer)\Trusted Root Certification Authorities\Certificates
In Certificate Authority, a right click on WHS-CA and looking at the properties, under General, shows 2x CA certificates:
Certificate #0 with validity from 15/03/2012 to 7/03/2052 and thumbprint 8a 5a cc 7c da 03 05 c6 d6 ff 7e 56 26 48 99 0d 1b 39 6d a8
Certificate #1 with validity from 2/06/2020 to 25/05/2060 and thumbprint 4a e7 2e 07 21 bd 08 31 da 2d 96 bb 7a dc 03 fd 8e 75 b6 73
These are the 2 mentioned in the log file.
When I couldn’t get the connector installed on the client PC, I exported Certificate #1 to a file and then imported into the client. The connector install on the client was then successful.
Looking on the client (WIN10 Pro) at \Console Root\Certificates (Local Computer)\Personal Certificates I see a certificate with the name of the client PC
Issued to DELL, Issued by WHS-CA, Expiration date 18/08/2050
It has a thumbprint of 49a921b7c43e63e78479bf1745aacd4d8e9496a7

That's where I am stuck.
It seems to be a certificate issue but I have no idea on how to remedy it so looking for assistance here.
Thanks, Phil
