[Samba] dos command "del" fails under 2.2.8

[rkpho at hotmail.com]

I can logon to Samba and map a drive letter (say "net use F: /home"), but I
cannot delete files under F: at the DOS prompt with command "del" (e.g.
"F:\>del xyz.txt"), the error says :

	The network has responded incorrectly.
	Abort, Retry, Fail?
