Is your win2k server networked? does it have multiple users? I would first
check the various profiles to ensure it was not moved to a different
profile. Next I would ask did the "administrator" install the server? if
another username installed the server even with admin rights that server is
now officially part and parcel of that user only. Next I would investigate
where the server was installed. There are a number of directories that are
auto deleted every time you reboot. Look for unusually large ~.tmp files.
Like ~exp0023.tmp or perhaps File00452.tmp. If the server crashes and a
program is up in memory windows has a nasty habit of spitting the file in
memory immediately to the disk without giving you more than a small hint
what the original name was. 

My suspicion is you won't find any of these. Here's a typical scenario...
The server is set-up with a cleaning scheduler. Every night at midnight the
system runs a virus check, a scandisk and a defrag then empties the temp
files and reboots. The Mysql program is running at the same time. Mysql is
using a section of memory that is also used by defrag. Microsoft sometimes
lets programs share memory space but some programs (virus checkers and excel
are the worst) fail to give the memory back. A good midnight query is run.
It crashes. The program is dropped into the Temp bin as ~ql883.tmp the
server runs the cleanup process and finds a huge tmp file it cannot put in
the trash bin because of it's size (mysql server + query + tables > trashbin
size) therefore for your convenience Microsoft auto deletes the file. Then
reboots. 

You might get a warning that the server cannot be found but that would be
it.

Subject: HELP - MYSQL databases disappearing!
Importance: High


Does anyone know why a MYSQL database would just disappear and how I might
prevent it from happening in the future?  I run it on win2k advanced server.

Much obliged,

Mike Taffi
