Server 2003 and NFS

I hope this is the correct group to post this.

I have a Server 2003 R2 system networked with a few Solaris (UNIX)
systems, and I'm experiencing difficulty mounting a UNIX-shared CD-ROM
drive to the Server 2003 system. The CD-ROM appears to map alright,
as I get a new network drive icon on the Windows system, but any
attempt to access the data underneath it results in the error "The
data area passed to a system call is too small." (This comes from the
Windows system)

I'm a little surprised (but not very) at this because I have several
UNIX file systems (UFS) mounted on the Server 2003 and they operate
without problems. I presumed the same would apply to the CD-ROM drive
since it was shared out as an NFS file system ("share -F NFS -o ro=<PC
hostname> /cdrom/cdrom0").

Can anyone suggest a route for troubleshooting this, if indeed it is
fixable?

Thanks
