Samba problems with file xcopy

[M.Hockings]

I'm trying to do some quick backups from a Win2K laptop to a Fedora Core 
1 desktop but it ain't working.  The backups are just a bunch of 
xcopy's. Most of them run fine but two fail and I don't understand why.  
It appears that xcopy is attempting to create directories in both 
cases.  When I run the backup targeting a Win98 desktop there is no 
problem.  Any ideas as to what the problem might be?

d:\>xcopy /S /Z /V /Q /Y /I /H /R /D /EXCLUDE:d:\bat\bu2x.exclude 
d:\ApplicationData\*  \\fc1\backups\ApplicationData\
Access denied Unable to create directory - 
\\fc1\backups\ApplicationData\nof7\Templates\MXTemplates
0 File(s) copied

d:\>xcopy /S /Z /V /Q /Y /I /H /R /D "D:\Program Files\NetObjects Fusion 
7\*"  \\fc1\backups\ApplicationData\programfiles\nof7
Access denied Unable to create directory - 
\\fc1\backups\ApplicationData\programfiles\nof7\Components\ApollonComponents
0 File(s) copied

Kind regards,

Mike
