Unable to add host to vcenter inventory

[PeterChanning]

I have hosts that I am unable to add to my vCenter inventory. Looks like a potential certificate issue.

In the environment I have 5 vCenter appliances. I have populated hosts and VMs in 4 of the 5 vCenters without issue. When I attempt to add any hosts into the inventory of the last vCenter, either through the web client or the thick client, I get the following error:

A general system error occurred: Unable to get

signed certificate for host: <HOSTNAME>. Error:

Failed to connect to the remote host, reason = rpc

_s_too_many_rem_connects (0x16c9a046).

(382312518).

The default self signing authority has been replaced with certificate from the organizations internal CA as a subordinate signing authority.

I have looked high and low for anything on this error and found nothing. Trying the forums today and will open a support request soon if I get no where with it. Any help is appreciated.

There is a solution for this, check this KB.
