Probably erring on the side of caution here, but i've not gone through this process before.
I have an SBS2008 server which is throwing a warning:
"The root certificate, which is used to create other certificates, will expire in less than two weeks. Before then, run the Fix My Network Wizard from the Connectivity subtab on the Network page of the Windows SBS Console. Then re-deploy the certificate package to your client computers"
Now i'm assuming it's an internal certificate (anyway to tell?), and i run the FMN wizard as it mentions, however i'm not sure if it will require any intervention on my behalf or whether the required files will be automatically pushed out to client computers etc?
Hope that's enough info. Thanks in advance for any advice.
