Re: Unable to start service OvCtrl The handle is invalid. (6)
Dear Sumit,

Out put should be like this:
C:\Documents and Settings\emsadmin>ovcert -status
Status: Certificate is installed.

But in your case:
C:\Program Files\HP\HP BTO Software\bin>ovcert -status
Status: Undefined (Certificate Client could not be contacted).

That means Agent certificate is not trusted or not installed properly.

Can you do below steps:
1.ovcert -remove
(removing all the certificates from node)
2.ovcert -certrq
(Retriggering the certificate)
3.Grant the certificate from OM server and check the ovcert -status if it is ok then kill the complate agent and start.

Thanks & Regards,
Suresh Reddy.
