How to re-generate expired ssl certificate in esx 4.0

[Beadmin]

Hello,

I want to re-generate, expired ssl certificate in esx 4.0.

I have reffered this :

http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=100909...

-copied rui.key, from v-center to laptop where open ssl is intsalled

- now from where should I run this command "

• openssl.exe req -new -x509 -days 3650 -sha1 -nodes -key rui.key -out rui.crt -subj "fqdn_of_VC"

its not working from the folder of that copied certificate or from c://openssl

Thanks in advance

I am a little bit confused as to why you need to regenerate your certificates, they are valid for 10 years, this would mean even if your installed vSphere 4.0 on release date you would not have to regererate until 2019.

Are the certificates self cert or properly signed by a CA?

Thanks Tom for the reply,

certificates on my servers were for 2 years and they have  already expired.

I mean the default Vmware self signed certificate and not the microsoft PKI or third party CA

Thanks
