Problem with mount hgfs

[Paulo Cesar Naves Mota]

Hello friends,

      I am with difficult on Red Hat 5.2 using vmware-tools. I installed 
the last version vmware-tools (VMwareTools-3.5.0*.i386.rpm), however,  
all time show me  the messages below:


[root at server ]# mount -a
Error: cannot mount filesystem: Protocol error

/var/log/messages
kernel: VMware hgfs: HGFS is disabled in the host

/etc/fstab
# Beginning of the block added by the VMware software
.host:/                 /mnt/hgfs               vmhgfs  
defaults,ttl=5     0 0
# End of the block added by the VMware software

   Someone know how to enable it?
   Can you help me about this?

   Thanks!
