I've made the change you suggested and I'm still getting "Error 3 copying file (The system cannot find the path specified.)"
This is the exact same message I described earlier. Any further suggestions?

$Fil = "localpolicy.inf"
$Src = "\\Server Name\netlogon"
WRITEVALUE("HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\SeCEdit", "TemplateUsed", "\\Server Name\netlogon\localpolicy.inf", "REG_SZ")
$DstSize = GETFILESIZE ("$Dst\$Fil")
$DstTime = GETFILETIME ("$Dst\$Fil")
$SrcSize = GETFILESIZE ("$Src\$Fil")
$SrcTime = GETFILETIME ("$Src\$Fil")
IF EXIST ("$Dst\$Fil") = 0
; REM ** File not found on client
COPY "$Src\$Fil" "$Dst\$Fil"
IF (@ERROR = 0)
? "Success copying file to client"
ELSE
? "Error @ERROR copying file (@SERROR)"
ENDIF
ELSE
IF ($SrcSize <> $DstSize) OR ($SrcTime <> $DstTime)
COPY "$Src\$Fil" "$Dst\$Fil"
IF (@ERROR = 0)
? "Success copying file to client"
ELSE
? "Error @ERROR copying file (@SERROR)"
ENDIF
ELSE
? "Verified file already exists on client"
ENDIF
ENDIF
