Our exchange database keeps unmounting during early morning hours
The drive that our exchange database occupied on our server was running out of space. So we put in a NAS, mapped an iSCSI drive, and used MS iSCSI initiator to connect to the NAS, moved exchange to that new iSCSI drive.
It was working great for the first few weeks however recently it seems that the exchange databse will become dismounted during the early morning hours. I only find this out when I see that my exchange email is syncing on my phone, after which I remote in, check mailbox store on ESM, and right click to mount the database. I've already tried restarting the server and the NAS and I have checked that the NAS should have plenty of space to accommodate our exchange database.
Any ideas on how to fix this? Thanks.

Currently our exchange database is at 38.9 GB. Exactly which log files would I need to check and where would they be located?
here is the link to the limits and reg key
Let me know if that is not the problem and we can look deeper

Seems like the link is down, i'll check and see if google has a cached version of it

If I wanted to backup the registry of win 2k3 server, is it the same process as the desktop variants? i.e. open regedit click on file and export?

Thanks, seems like the Database Size Limit in Gb entry was already present. It was set to 24, and i upped it to 75. Will see if exchange dismounts again tonite and if it doesnt, hopefully i'll throw you a party tomorrow with 500 points
Sweet. I would reboot server as wellafter reg change
Or restart exchange services
Or restart exchange services
I wouldn't set the limit to 75Gb - it won't give you any play when your database grows to 75Gb - you will then have to panic!
Set it to about 70Gb - which gives you 5gb spare and time to beat your users up to archive / purge their mailboxes.
You don't need to restart the server for the setting to take effect.

restarting exchange services sounds easier, which services do i need to restart?
Just restart the Exchange Information Store service.
information store

good point about the 75 GB, I will reset it to 70 GB

It seemed like that was exactly what my problem was. A 500 Point Party goes to the expert with a sys admin password as a name!
Any event logs relating to size? You may have plenty of free space, but you may need to change a registry key to allow your DB to grow larger without dismounting
