I?ve had issues with Win 7 logging on slowly after I?ve included it in my PDC (samba v3.4.9-60). After some googling I found this link: http://blog.bigsmoke.us/2010/03/17/fixing-extremely-slow-domain-logon-windows-7 I tried it out and I thought my problem had been fixed after I rebooted and logged into my computer once. A few days ago I tried doing the same thing again and it was again dirt slow to log in. Yesterday I noticed there were a number of instances of my user cache in the computer (user.DOMAIN, user.DOMAIN.001, user.DOMAIN.002, etc.) ? I suspect these directories were being created as I logged in each time. Has anyone seen this? Thanks, - Joe
