Linux NTFS – Mount NTFS Filesystem on RHEL 5 with Read/Write Capability

To me it sounds like a Windows bug. There are a few things that you can do one place but not others, and in my experience a few more of those crept in with 2008 R2. You may have found another one. The fact that an NTFS partition could be put on there at all, especially in diskmgmt, suggests that there is no problem with it. That MMC is as close to the One True Disk GUI for Windows as Windows gets, so that option not being available in the Exlorer Format menu is not a red flag for me.

For network windows shares you need to specify the uid/gid that the drive should be mounted as and/or the file and directory modes to use since Windows doesn't understand Unix users and Linux doesn't understand Windows users or permissions. Right now, the share is probably writable but everything is owned by root so no other user can do anything.

Try:

mount -t cifs -o username=winuser,rw,uid=linuxuser,gid=linuxgroup //192.168.15.10/Web /dev/fileserver

Where linuxuser and linuxgroup are both your username in Ubuntu. If you need to make the windows share writable to everyone, then you can use ,dir_mode=0777,file_mode=0666 instead of uid= and gid=. If you need some people to have access and others not to, then you can combine both of them:

mount -t cifs -o username=winuser,rw,gid=somegroup,dir_mode=0775,file_mode=0664 //192.168.15.10/Web /dev/fileserver

which will give write access to all members of somegroup but everyone else will only have read access.
