Event ID 2021 Repeatedly logged following file move

Hi,
Upgrade time!
To reduce load on our primary exchange server/DC, which was operating extremely slowly, I moved the main file store to our secondary DC (also a GC server) which also acts as a SQL server and print server. I have a third server to take over as our exchange server, which I'm currently setting up, and a NAS box which I've bought as a backup to disk folder. The third server won't be ready for a week or so though, it's a swing upgrade.

The exchange server has improved, with less timeouts responding, but the secondary DC is now reporting a large number of warnings (1 every 2 minutes), below.

I haven't yet copied back all the files as I don't want to have a knee-jerk reaction to this issue. I've found some MS articles on this which suggest modifying the registry. What's causing this and is registry change the best method?

Thanks,
Chris.

Hi andyalder,
I've maximised resources (part 1) using the network configuration, the warnings still occur.

I was a little twitchy about changing the registry settings, especially whilst users are logged on. The article also doesn't advise whether a reboot will be necessary.
Any steps I should take beforehand, or just carefully change the registry as per the article?
Chris.

Reg settings won't be dynamic, you'll have to reboot for them to take effect. HAve you tried increasing the RAID controller write cache percentage? That can normally be done live.

No - will look into the RAID change tomorrow; users are heading off home shortly, so I'll give the registry change settings a try first. Made the changes, will reboot later this evening and let you know...

The MS article http://support.microsoft.com/kb/317249? has so far solved the problem. Either that or staff aren't working too hard yet, it is a friday after all.

Regarding the RAID settings - what impact will this have, and is this a risk? I've downloaded IBM ServeRAID and reading through the install documentation before proceeding.

Regards,
Chris.
