Don't think so, server is stable since FM installation several months ago. However, a few hows prior to this problem appearing I added two files to the server. These files (well, one, because one is multi user hidden) appear in the local list no problem (until thelocal list disappears altogether).
FWIW, the server runs W2000 5.00.2195 SP2. FM Server is v 5.5 (sorry, not 5 as I stated above), and the clients are mostly 5.5v2 (N) with one or two v1 (according to the application service log).
I'm not able to identify yet if the disaapearance of the local list is related to a client trying to connect, or if it is a server software problem (OS or FM). I cannot find any logged events that would appear to trigger this or coincide.
Again, it is possible to connect specify the IP address of the host/server.
