That is a Windows error, a quick google revealed this link:
It revolves around Windows wanting to install an expired root certificates update.
From a newsgroup post: "I have manage to solve the this error by downloading the authrootstl.cab manually and installed the certifcate manually too. I have not seen the error event anymore since then. I also replaced the crypt32.dll just to be on the safe side."
Hope this helps.
This error being due to the fact that the server does not have Internet access to update its root certificates.
The easiest thing to do is to remove this feature, as it is redundant in this scenario:
1. Goto Add/Remove Programs > Windows Components
2. Untick Update Root Certificates and click next
Thanks a lot ! - problem solved.
