I have tried installing p4 recently only to find that all my older 95 (pre OSR1 or whatever it was called) and WfWG clients can no longer connect to any shares. I am using 'security = server' and the later 95 and all NT clients can connect. I have looked through the documentation and can find no newer options that might affect my setup. Is there a bug here or have I missed something obvious. The last version that I can swear by as working correctly was 1.9.17p2.
