Please help me!

Problem:
Our main server crashed this afternoon.  I believe the crash was caused 
by a MAC user trying to install a program from the network.  (He was not 
supposed to do this, but unfortunately I didn't deny access to the 
directory.)  

Details:
We are running Novell 3.11
I downed the server and brought it back up.
SYS volume would not mount.
I ran vrepair and it found many errors which it wrote to disk.
I downed the server and brought it back up again, this time SYS mounted.

Now, no one can login.  When anyone tries to login the server console 
gives the message:

NCP request received with invalid security signature.
Possible intruder or network corruption.

None of our users have passwords.  I can't even login as supervisor with 
the right password.

What I've tried:
I believe the bindery has been corrupted, but I can't restore it because 
I can't login to the server from a workstation.  Bindfix & bindrest are out.

I tried copying the system directory from another server to the troubled 
server, downed it, brought it up, no change--still can't login.

I want to run vrepair again, but can't seem to get the SYS volume NOT to 
mount so I can run vrepair again.  It doesn't find vrepair if I mount 
then unmount the SYS volume.  I tried a boot floppy but must have done 
something wrong because it can't find any volumes to repair when I try 
vrepair from the floppy.

I'm trying right now to use sbackup's restore function.  We have a fairly 
new tape backup on one of our other servers and luckily I backed up the 
crashed server a couple weeks ago.  I'm having trouble restoring the 
bindery though.  It's going now but the Total Restored amount has said 
326.5 KB for over 32 minutes.  I tried stopping it and restarting it, 
restoring not just the bindery but part of the sys, but this also seems 
to stick at 326.5 KB.  It is currently attempting to restore still.  I 
haven't stopped it yet.  The Activity bar is going across normally and I 
haven't received any errors, but I'm just concerned about the Total 
Restored amount staying the same.

I've been working on this for over four hours now.  Any suggestions are 
greatfully appreciated!

Thanks,
Jessica
