Yes.  This was resolved.    Here are the instructions that were provided that resolved the issue.

4) Note that if the workstation being used with office integration is a terminal server, which I believe you indicated that it was, once a third person is signed into the terminal workstation, all default ports will be used. If more than 3 people will be logged into the server at once, we have some additional steps that can be taken to provide more ports values for webtools agent. I'll be attaching screenshots of examples of what the following two configurations should look like. The values in the screenshots are just examples and you can use the guidelines below to adjust those values:

A) In web client, this value will be added as an attribute named "[Options]WebtoolsAgentPortRange" to the Everyone group under Management > Everyone, with range value in Data

B) For Webtools Agent, create a subkey "Computer\HKEY_LOCAL_MACHINE\SOFTWARE\LASERFICHE\Webtools Agent" and add string value named "PortRange" with range value in the data column

Valid port range is 1024-65536 (Port 0-1023 are reserved for common TCP/IP applications). Note that we support the following port range formats which you can include in the above two configurations:

Range: "100-200"
Single port: "200"
Multiple ranges: "100-200,300-400",
Multiple ports: "100,200"
Combination of ranges and single ports: "100-200,300"

It's called out briefly in https://support.laserfiche.com/kb/1014418/list-of-changes-for-laserfiche-windows-client-11-update-3 . The idea is that in both the repository attributes and the registry on the client machines, you can specify a port range to use, something like "12000-13000".
