We have an SBS Server 2008 running Exchange, DNS, AD and File services. WSUS was taken off this server and is being used on another server and only updates client PC's.
When trying to get MS updates for this server, we get the 80072efd error. After this, we found that in IE or Firefox, https sites like https://www.google.ca
simply will not come up and we get the standard connection error and option to run Windows Network Diag's. Running the Windows Network Diag says that there is a firewall in place somewhere blocking 443 access, even though the test site (Google.ca) can be pinged, and nslookup does resolve it.
The weird thing is http can be searched in both browsers.
I tried resetting IE, Firefox, both netsh for winsock and TCP stack, firewall is off on the server, everything else is fine but still https will not come up. We use a Sonicwall TZ205 but there does not appear to be any blocks in place for it to get https traffic, and it does have a rule for its OWA port and that does work.
Need your help folks. At a loss as to what to do. Could it have been WSUS when removed broke the https access? I did follow the MS KB's on removing the WindowUpdate AU from registry, but it was not there to start with. No other servers or PC's have this issue, only the SBS 2008 server. Tried to reinstall WSUS from the Roles and get same error as the updates basically, since it is looking for updates via https!
Your help is very much appreciated.
