Hi folks, Everything has worked great until recently when some NT boxes are no longer able to browse the Samba Server. I can still map samba drives by specifying the exact path, using Find Computer in NT Explorer, or NET USE use from the command prompt. Most boxes are still fine. No change occured with NT, AIX, or smb.conf when this happened. I tried increasing os level to 34, and specifying preferred master = yes. wins support has always been yes. Will updating from 1.9.16p7 to 1.9.18 help? Super Dave
