I'm seeing some strange happenings on my network. Users sign in and the login script maps correctly most of the time. However, there are sporadic occasions where the script will not map network drives, instead mapping search drives to the local hard drive. I've sat at a workstation and logged in over and over again. Most of the time it's fine, but the other times, the users aren't getting their required network drives.

These are Windows 7 Pro 64 bit workstations using NC2 SP2 on Netware 6.5 SP8. I know Client SP3 is out, but before I spend days updating clients all over my network, I want to know if anyone else has experienced something similar.
