I started getting this event on NODE 2 repeating over and over.

I restarted IIS  by doing IISRESET   still the event continues.

Check your certificate

Hi,

Like David mentioned above you may want to check your certificate. Select your SSL certificate and set your binding to use https.

Generally:

  • Open IIS manager.
  • Select your website and click 'Bindings' in the right frame.
  • Select https and click on 'Edit'.
  • Select the SSL certificate that you want to use and click 'OK'.
  • Restart IIS.

As for Kemp specifically read up here.

Dave/DFKE,

Thanks for the reply's.

I never had a SSL on this before just wondering why it is thinking I did ?

I just updated the cert about a month or so ago.

I do redirect HTTP to HTTPS on the Kemp.

Will look into getting SSL for my Web Services   I will post results

Thanks

Guys,

I already had a cert on my exchange servers    I just exported the cert and imported it onto both my web servers.

Then imported it to my kemp    now kemp has all green and my web site is back online both internal and external.


Thanks for all the help
