为什么我用mount -t smbfs -o username=administrator //ip/盘符$ 目录名/ 不能

watershed

[/]＃mount -t smbfs -o username=watershed //10.1.151.145/e$ /home/oracle/win_dir
1869: session request  to 10.1.151.145 failed(called name not present)
1869: session request  to 10 failed (called name not present)
1869: session request  to  *SMBSERVER failded (called name not present)
SMB connection failed.
我的版本是EL3，windows的用户watershed有管理员权限，请高手帮忙！
