Access problem on mount

Hello,
I used sudo mount command to mount external window drives

sudo mount -t smbfs -o noowners //winuser:winpwd@winsrv/shareddrive /winsrv/shareddrive

Click to expand...

Now I cannot access /winsvr/shareddrive but I could able to access using sudo ls -l. I tried to chown me:megroup /winsrv/shareddrive. But still not able to access. Please let me know how to access /winsrv/shareddrive
