How To Get In A Mess In 1 Minute :)

Ok Guys

I have no doubt screwed up through my lack of knowledge.

I have been running WHS 2011 for years no issues backups etc etc working fine.

The past 2 weeks my main Desktop has stopped backing up Critical failure at about 2% it stops.

First error i thought that having tried it about 10 times i would remove it from the server backup and add it back.

When i went to add it back and reconnect with  a new dashboard. I then hit my next error common fault  ' Unable to Establish a Trust Relationship' So after a few days i found this article below whichh i thought worked it connected me and everything looked correct.

But when i went to reconfig backup it sees my new PC but the options to backup are missing and it does not recognise what O/S my desktop is.

See screen shots here:

Anybody please help me why am i not able to backup?

I tried this article i found it sorted the 'Unable to Establish a Trust Relationship' issue but i still have the other problems as shown in the images below.

1. On the WHS, launch Certification Authority from the Administrative Tools menu
2. Right-click on the <Server>-CA node and select Properties.
3. In the Certificates tab of the Properties window, you should see at least two certificates, numbered sequentially.  Double-click the newest certificate.
4. In the Certificate window, select the Details tab, and click the Copy to File button
5. Step through the certificate export wizard, choosing any of the first three formats (I used the PKCS #7 format, and selected to include all certificates in the certification path).
6. Save the file to a location that is accessible to the client you're trying to connect (or a USB drive).
7. On the client machine giving trust issues, open the certificate management console for the local computer by performing the following:
8. From a Run line, enter mmc.exe
9. In the empty console, go to File -> Add/Remove Snap-in
10. Double-click Certificates
11. Select Computer Account and click Next
12. Choose Local Computer, and click Finish
13. Find the Trust Root Certificates node, and expand Certificates
14. From the Action menu, Choose All Tasks -> Import
15. Ensure that the Store Location is Local Machine, and click Next
16. Browse to the file you exported earlier, click Next
17. Finish the wizard, and ensure that the new certificate appears in the certificate store
18. Re-run the Connector software.  It should now run successfully.
