I've put in a Samba 2.2.5 PDC that runs a logon.bat for every client (NT4 & W2k). The logon.bat mounts a single share. Some users are experiencing this share getting re-mapped _many_ times through out the course of their session. In other words, a user logs on and the logon.bat maps P:\share. Then, a couple of hours later, they will have Q:\share, R:\share, S:\share, etc. Ive seen a dozen or so duplicate mappings in a single user session. I've searched the internet as well as these archives without any clues. Anybody seen this? thanks Gordon
