I'm getting a "mount failed: input/output error" when mounting a directory on a WindowsXP using SMBfsys. This is the 
first time I've come accross this error and don't have any idea what could be causing this.  This setup have been 
working great for the past month.  My mount options in sysinit.1 are as follows:

SMBfsys &
user_smb dt500 viewtrak
mount -t smb //SH:10.1.9.239/TC_data /usr/remote

Any information would be greatly appreciated
