I am currently using VMware Vsphere 5.0 and got no issues on it. Now I just want to test VMWare Vsphere 5.5. and encounter these concern, vCenter Server 5.5 for my VMs have an error of "Unable to contact lookup Service. Check vm_ssoreg.log in the system temporary folder for more details" "Error 29102". Can you advise on how to fix this?
Cause
There are several causes for this problem:
· unsynchronized clocks from host machines
· firewall blocking
· services that must be started; etc.
Solution
· Check the clocks on the host machines running
· vCenter Server, vCenter [Single Sign-On], and the Web Client are synchronized.
· Find out the exact log file found in the error message
[system temporary folder refers to %TEMP%].
· Find the message in the log file [The log file contains output from all installation attempts. Locate the last message that shows Initializing registration provider…].
1. Make sure that a firewall is not blocking the vCenter [Single Sign-On] port.
2. vCenter Single Sign-On is installed [The machine has sufficient free CPU, I/O. and RAM capacity].
3. Check that vCenter [Single Sign-On] is working:
· vCenter [Single Sign-On] service (Windows)
· vmware-sso daemon (Linux).
4. Finally, restart the service.
5. Be sure that the configuration for using the FQDN on the right of “!” sign [ otherwise, recover your vCenter Single Sign-On SSL configuration].
