I have a NW 6.5 sp5 server that is showing a very high number of
'Failed Logins Per Hour'. All the login attempts are as follows:

Time: Tuesday, 3-20-2007 9:20 am
Address: IP

The user is the MTA within a GroupWise system. The server showing the
problem is 1 of 3 POs in a GroupWise system. The other 2 POs do not
show this problem. The only thing different about this one is that it
is running iManager. I have seen several mentions of this problem but
I cannot find any resolutions. I would appreciate any information on
why this is happen and how to stop it.
