Hello,
I get this error when trying to add our VCenter server to SCVMM 2008.
I have ensured that the VCenter certificate is imported into the SCVMM server.
Error (12703)
VMM cannot establish a trust relationship for the SSL/TLS secure channel for VCenter server.
Recommended Action
Install the certificate to the trusted people root store of the VMM server and then try the operation again.
The only thing I notice when I look at the certificate is that it is the self-signed autogenerated cert that VCenter creates durring its initial install, and it has an expiration date of 5/16/2007....and under certificate information it says "this certificate has expired or is not yet valid"
I am assuming this is the problem? Can anyone confirm this?
If so is there any workaround? Aside from reissuing certificated for our VMWare environment (which according to doccumentation requires some significant host downtime)
Thanks for any help at all, I would love to be able to get VMWare and SCVMM working together, it would make life around here sooo much easier.

Your Virtual Center server was probably installed a few years ago and the VMware provided certificate seems to have expired. The certificates in Virtual Center will last for 2 years per default. The VMware Infrastructure Client will still work fine, but System Center will complain about this. You're not the first one to experience this issue while trying to get SCVMM working.

Just to explain this problem a bit
when you add the virtual center server you have the option of choosing whether or not you want secure or unsecured mode. Secured mode basically means it will connect via SSL but the certificate must be valid and added to the VMM servers trusted store.
in your case it is in secure mode and the certificate is expired, like larstr said. It is probably an old install and the cert has expired.
you have two options
option 1 is to upgrdae your SSL cert on the vmware server

option 2 is to remove your virtual center server and readd it in unsecure mode.
Good luck, hope that explains it.

Ben,
You will need to create a new certificate for your Virtual Center:
