Everything on my network works fine. Logon scripts run on the new Windows XP Pro machines (we have an NT4 domain). But, one of my administrator guys mapped a network drive on a couple of PCs as his account (he was a local admin on the machines) and now it seems every other normal user who logs on to these two machines doesn't get their login script drives mapped. It seems to be because the %systemroot% variable is not working properly. The PCs are not seeing "net use" as an allowable command. I have to type c:\windows\system32\net use... " to make it work. If I change %systemroot%\system32 to c:\windows\system32 in the environment variables, then it will work without having to go to c:\windows\system32 first. What causes this? It only seems to be after as administrator maps a drive with the "map network drive" tool on the tools menu of explorer.
