samba - Jan 2003 - Samba 2.2.3a Bug ? Share with msdfs root=yes: NT 4 client can't create directory

Hi,

we use in the subject mentioned samba 2.2.3a share. All works fine, but NT4 
clients can't create directories (Error: no such file or directory). W2K 
Clients does the work without any problems. Is it a problem of samba, NT or 
a error in our configuration ?

Thanks
