Exchange 2007 on SBS 2008 OWA and Outlook anywhere issue : ASA temporary certificate
We encounter a certificate error on one SBS 2008 server. It is impossible to connect to OWA from the outside (cert error and redirected to the "+CSCOE+/wrong_url.html" Wrong URL page) or with Outlook anywhere (proxy server's security problem) since yesterday evening. We can connect to OWA from the inside, the certificate is alright then with the good subject name (domain.dyndns.biz) and is valid up to 2014.
I checked the certificate from the outside, it is issued by "ASA Temporary self Signed Certificate" to himself and is valid to 2023. The error message is about trust of the certificate that have to be installed in the trust root store...
The ASA temp cert seems to be created by the Cisco ASA of the customer, I can't find the way to remove it...
There are some errors in the certmgr.msc snap-in : AIA Location #2 , DeltaCRL Location #2 and CDP Location #2 are "Unable to Download", I don't know if it is linked.
With Android smartphones there is a authentication error but everything is fine with BB phones.
