I moved our installation to a new server and was following the Administration Guide.  The old server is v9.2 on Windows 2008 R2 with SQL 2008 R2 Express installed with v9.2.  The new server is SQL 2012 R2 with SQL Server 2016 Express installed before v10.2.

After unregistering the v9.2 repository, stopping the Laserfiche server, detaching the LF database and copying the files to the new server.  I uninstalled the v9.2 Laserfiche server.  On the new server, I attached the LF database and ran the v10.2 installer.  During the installer I entered the activation key from our company profile.  Then I registered the repository which upgraded the schema and deleted the .IDX files and recreated the Index.  The Administration Console is showing the "localhost" server status as "Online".  So everything appears to be running okay with no errors in the Event log, but the 10.2 client installed on the new server can’t connect and is giving.  Same error trying to connect from a 9.2 client computer.

During the 10.2 installation it appeared that the firewall was adjusted for Laserfiche connectivity and the same entries appear on both the new and old server firewall incoming rules list.

What else besides checking the checking the firewall ports would cause this issue?
