can someone help, i am running sbs 2008 with exchange 2007, i got an error from the daily network report that 'The certificate that is helping to secure your Web site traffic 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. I dont want to run the wizard as my router's firewall is preventing the access to the server. when i attempted renewing via exchange management shell, i got a warning which tells me to overwrite the default smtp certificate (which will expire in the future, 2013) i want to know 1)what is the implication of overwriting an existing certificate which is yet to expire with a new one (note they are self signed) 2)Should I remove expired certificates from the server?
