I'm having a hard time finding conclusive evidence on this: did MS put any kind of maximum concurrent TCP connection limit in Windows Server 2003 and/or 2008? (The equivalent of the XP SP2 "feature" they added...)
We're relooking at part of our architecture which is currently based on other technologies with using NetBIOS, but we'd need to be able to have 50-100 hosts connecting to 20-30 other hosts all over NetBIOS directly. Obviously a 10-connection limit (as it is in XP) will put a quick end to that particular plan.
