Unable to connect to a ESXI server via Vsphere client.

I'm unable to connect to my ESXi server using Vsphere client. The client is installed on a XP machine (Version 5) and ESXI is 5.1.0

I can ping the ESXi server from the xp machine. And I can connect with another PC (windows 7 installed) but not with the XP PC

Error when attempting to connect  -

AN UNKNOWN CONNECTION ERROR OCCURED. THE REQUEST FAILED BECAUSE THE CLIENT COULD NOT VALIDATE THE SERVERS SSL CERTIFICATE (THE UNDERLYING CONNECTION WAS CLOSED; COULD NOT ESTABLISH TRUST RELATIONSHIPS FOR THE SSL/TLS SECURE CHANNEL?))

Any assistance would be appreciated.

can you connect via IP Address or FQDN?

can you test the following:-

telnet <ip address> 80

telnet <ip address> 443

telnet <ip address> 902

if you connect via a browser to http://<ip address> do you get the vSphere ESXi web page?

I tried to access via the browser but it failed.

I only tried connecting via the IP address and not the name.

are you sure you have the correct IP Address?

any firewalls in the way?

what are the results of the telnet tests?

Don't lose your head updating email signatures!

Do your end users still have the wrong email signature? Do email signature updates bore you or fill you with a sense of dread? You can make this a whole lot easier on yourself by trusting an Exclaimer email signature management solution. Over 50 million users do...so should you!

Have a look at this article:

To resolve this issue, install/reinstall Microsoft .NET Framework 3.5 Service Pack 1 or later.

Cheers,
Steve

Good trouble shooting tips all round. I re-installed .net and it seemed to do the trick but I think our network team also configured something - thanks anyway.
