If you have CSNW or GSNW installed, and you try to logon immediately after start up, your Netware logon scripts don't run. If you wait a few minutes, or logoff / logon, they do run?
The problem is that the Netlogon service is started before the Netware client process.
To fix the problem, use Regedt32 to navigate to:
Double-click the List value name in the right hand pane.
Click in the Multi-String Editor to remove the selection highlighting.
Scroll down the list to NetBIOSGroup.
Remove the entry and add it to the end of the list.
Add a blank line after the NetBIOSGroup entry.
On the Edit menu, Add Value name Group as a string (REG_SZ) data type.
Type NetworkProvider into the String Editor.
Exit Regedt32 and restart your computer.
