I have basically the same problem. With the server running on Vista, no other Vista machines can connect with the exception of the host (ie client/server same machine) I can log in on the LAN with an XP machine.
Have tried running the start.bat as administrator in XPSP2 compatibility mode, running the vista client eqgame.exe as administrator & XPSP2 compat mode,binding eqgame to a single core with all firewalls dropped and no authentication required for file shares - no joy. Vista client can join to other Eqemu servers such as PEQ (but I believe that has a linux install?) At least I have the XP machine as a backup but would eventually like to go VistaClient-VistaServer. And yes I've followed the Vista guides in this forum
