I have an sbs2008 that was set up about 5 months ago, people have been logging in remotely, i.e.
all this time for accessing their computers and all has been great. Just today, everyone started getting certificate errors and the 403 - Forbidden: Access is denied error and cannot get past this - different locations, different browsers. Can't get thru to server at all remotely. Is this some kind of outside attack? The certificate doesn't expired for another 6 months at least. any ideas?
