Certificate Revocation Issue

Exchange 2010: Certificate Revocation Issue

On a windows 2008 R2 and Exchange 2010 SP2 RU2, after importing the certificate via EMC on a new server, certificate is showing red circled cross and shows the status

“The certificate status could not be determined because the revocation check failed” 

Troubleshooting:

Exported the cert from other server and imported on this new server.

Exported the cert from one other server and imported on this new server

Configured the proxy on internet explorer and selected checkbox “Bypass proxy server for local addresses”

Exported the cert from other server and imported on this new server

Open certificates (local computer) and verified the chain is in place in intermediate and root cert authority.

Open the cmd prompt with run as administrator and Run the cmd

netsh winhttp show proxy

But got the below output which was saying no proxy configured

"C:\windows\system32>netsh winhttp show proxy

Current Winhttp proxy settings:

Direct Access <no proxy server>".

So run the following cmd as per kb http://support.microsoft.com/kb/979694?wa=wsignin1.0

netsh winhttp set proxy proxy-server=”http=myproxy” bypass-list=”*.host_name.com”

Now cmd “netsh winhttp show proxy” was showing the proxy details.

Run the following cmd to Check validity of the URLS in the cert

certutil -verify -urlfetch C:CertName.cer
