LMS 4.0 Remote Access Issue

[Marvin Rhoads]

My issues is that I cannot remotely access my LMS 4.0 installation. On the server itself, the UI comes up immediately (via https) in a browser. If I browse to the server using http (from the server itself), it redirects to https and comes right up also.I'm using a 3rd party (Thawte) certificate which seems to be installed properly - certificate info is retrievable from the browser address bar.

When browsing to it from a desktop, the attempted connection times out.

My normal method is to point to the server's FQDN (it resolves fine via nslookup of ping servername) but I have also tried using the server's IP in the URL, still no success. I captured the traffic from my desktop at the server using Wireshark. I see the incoming https traffic (syn, syn, syn - never an outgoing ack).

Suggestions?

addendum:

The system is listening on port 443. Partial output for "netstat -a" follows:

Active Connections

This sounds like a host-based firewall preventing the SYNs from making it up the stack.  Disable all IPS functions on the server (e.g. Windows Firewall), then see if you can access the server from remote.

That was it. Thanks, Joe.

Somehow Windows Firewall got turned on between last week and this week. Perhaps one of the recent Windows Updates started the service.
