Besides the obvious need for a couple UPS units, you could also change
your network settings. On your 486/95 machine which is mapping the P/98
drive, go into right click on "network neighborhood" and click
properties. Then double-click on "Client for microsoft networks" and
choose the "quick logon" option. This will prevent the mapping of the
drive until SDR actually needs to use the connection to report an event. 

If SDR checks the connection upon start-up (I don't know because I don't
use it) you will need an application that delays the startup of SDR. I
have such an application which is run in the startup group, and it can
execute multiple applications in order at ten second intervals. We use
this in some of our systems which run applications that use more RAM
while starting than while running, so by launching them one at a time
fewer resources are required.

Another utility we have can launch SDR with a command from the OTHER
machine, so when the slower machine finally boots up it can send the
command to launch SDR to the other. There are also several other
functions of this application, such as re-booting, checking running
applications, maintaing disk space and testing network connections... all
from the remote machine.

Let me know if you need any of this stuff.
