An internal transport certificate expired.

We are running Small Business Server 2008 with Exchange 2007.

I'm getting the following message in the log:

An internal transport certificate expired. Thumbprint:9790AE5E955202AE4478D4C5B4ED7EEA80714BC7

Full error message:

Do you know if this is a SS (Self Signed) certificate?
If it is then as it has expired I would think about installing a Trusted Certifcate from or a trusted certificate provider of your choice.

The existing cert has clearly expired so the only option is to either renew the one you have or install a trusted cert that will be a lot more secure.

How do I find out what certificate has expired ?
On the SBS server
Start > Run > type MMC
Then from the console goto 'File' > Add Snapin' > Choose 'Certificates' from the list of consoles > Click the 'Computer Account' radio button > Click 'Finish'.

From the console in the lefthand pane click on 'Intermediate Certification Authorities' and then click on the 'Certificates' sub folder. This will then disaply the installed certificates in the righthand pane and one of the columns in the console is 'Expiry Date'.
