What is failing to work now, though, is the original issue that I posted about. Initially I was concerned that if I tried to publish from the login AD-ENT\a115809 from workstation 1, it would overwrite the server timeline I had already published for CIBNA\a115809 from the same workstation.
Well, after renaming the existing timeline, to make it unabiguous (and more readable), I attempted to publish the second login from the same workstation. There was no overwriting, but the server fails to "take" the additional timeline. I tried it with the Computer Activity timeline, first, since I don't care so much about that one, and could live with it being clobbered.
While the manictime client says it has "Sent in the last minute", the additional timeline does not show up as existing on the server, either in the Timelines view of the server, or available for subscription from another client session.
This is not an issue of too many timelines on a MSSQL-CE session. If I unpublish some other timeline that works, to "make room", I still cannot get the new timeline to show.
