Exchange issues

Problems with renewing my exchange certificate. I was getting the following error:

[PS] C:\windows\system32>Get-ExchangeCertificate
The Exchange Certificate operation has failed with an exception. The error message is: Unknown error (0xe0434f4d)
+ CategoryInfo : InvalidOperation: (:) [Get-ExchangeCertificate], LocalizedException
+ FullyQualifiedErrorId : B5063A5B,Microsoft.Exchange.Management.SystemConfigurationTasks.GetExchangeCertificate

After searching the internet there was a suggestion to start the IIS Admin service.  The service was, indeed, disabled.  Starting the service resolved the issue.
