We have two servers that are both exhibiting bizzare behavior. The first
thing you notice is that they are not available on the network. When you go
to the console and login, the mouse cursor is out of control and wanders all
over the desktop, unusable. Then you Ctrl-Alt-Del and restart the server. It
hangs on the way down before it leaves windows all the way, blue windows
desktop but no icons.  At that point you hard reset it and it comes back up
okay and is fine for a few days until it happens again.
When viewing the system event log the only error you see is:

PlugPlayManager Event ID 12
The device 'MATSHITA UJDA780 DVD/CDRW'
(IDE\CdRomMATSHITA_UJDA780_DVD/CDRW_______________CA21____\5&871aba8&0&0.0.0)
disappeared from the system without first being prepared for removal.

Whe you look at the application event log, about thirty seconds after the
Event 12 error, you start seeing errors indicating the loss of network
activity, cannot find the DC etc.

One server is WIndows 2003 R2 Standard and runs a web application on an IBM
x3250 box.
THe other server is Windows 2003 x64 and runs Exchange 2007 Client Access on
a IBM x3350 box.

All the firmware on the servers is up to date and all the micirosft updates
are installed.
