SBS2008 - Self Certificate Expiry

Hi

I haven't done this for 2 years. I was hoping someone can confirm to me what I need to do. to give it another 2 years.

On an SBS2008 server I am looking after their Self Certificate is coming up to the expiry point. Obviously this needs to get renewed by the SBS server.

If I remember correctly, All I need to do is run the Fix My Network tool under Network and Conenctivity and this will refresh the certificate giving it another 2 years.

Can someone confirm this is correct, or correct me on what I need to do.

Thanks

Tris
