[Helder Miguel Rodrigues]

Hello!
Im trying to mount the ADMIN$ share of my windows XP and i cant!

I can mount other shares.

I do
./smbclient -L 192.168.0.18
added interface ip=192.168.0.1 bcast=192.168.0.255 nmask=255.255.255.0
session request to 192.168.0.18 failed (Called name not present)
session request to 192 failed (Called name not present)
Password:
Domain=[WORKGROUP] OS=[Windows 5.1] Server=[Windows 2000 LAN Manager]

         Sharename      Type      Comment
         ---------      ----      -------
         IPC$           IPC       Remote IPC
         SharedDocs     Disk
         dev            Disk
         ADMIN$         Disk      Remote Admin
         C$             Disk      Default share


and next i do

./smbmount "\\\\192.168.0.18\\ADMIN$" /mnt/laptop/ -o 
username=Administrator password=mypassword

and i get
30631: session request to 192.168.0.18 failed (Called name not present)
30631: session request to 192 failed (Called name not present)
Password:
30631: tree connect failed: ERRDOS - ERRnoaccess (Access denied.)
SMB connection failed

Do you know why? Do you know how can i solve the problem?
