System crashes at regular time

My system crashes almost every night within the same 20 minute window. The
physical server has the normally green on/off switch glowing orange as
though it's in a power save mode but the server has to be unplugged to get
it going again.

The server is on a UPS so I don't thinks it's due to an external problem and
the regularity makes me thinks it's not power supply.

Has anyone come across this type of problems before or does anyone have any
ideas as to how I might track down possible causes.

Thanks

Branston,

I just thought that I should recycle this recent post by Jeff Middleton
(read below).

BTW, what error appears in the logs???

HIH,

Javier

Yes... you have to set that exclusion in the NAV on the SBS server and:

c:\pagefile.sys
C:\Program Files\Exchsrvr\mdbdata

Probably there are more... (btw, the M: drive shouldn't be backed up either)

Any AV for SBS/Exchange doesn't require to scan the M: drive.

There are specific exclusions for NAV on SBS:

Go here for all the exclusions:

That should do it.

First I would look at what programs such as Backup or
Antivirus are running within that time window, but I
would like to draw your attention to another possibility.

I have seen problems similar to this being caused by
temperature. We are in summer. Many office buildings
will turn off their AC overnight. Not only does the
temperature rise throughout the building, but many
servers are in utility closest with no or limited
ventilation. The space slowly heats up until the server
crashes. By the time the staff shows up the next morning
the AC is back on and no one would think it could be the
culprit.

It is worth checking into,
But that is just my opinion...I could be wrong.

It could also be a marginal power supply, where running the tape drive
creates just enough extra load to max. the PSU out...
