Having BES issues, will this work?

[scott0482]

Ok.

We are having issues with a BES Express server. I don't know what happened. The thing ran perfectly for months, I go out of town, and it quits working. I have someone go into the office, shut off the server, fire it back up and it works for a few hours then freezes to the point where we can't get to it remotely.
The next morning I have someone else restart. I connect to it for a good hour everything seems fine, except BAS-AS service is using 350mb of ram and using a ton of cpu on and off..
Either way it craps out after a few hours once again.

So we uninstalled the antivirus (Webroot Corporate Edition) and that seems to keep it from messing up.
So it probably has to do with webroot. Maybe I have to make exclusions of what it scans. Maybe someone got a virus emailed to them that slipped into the bes server, and webroot and BAS-AS were fighting over it.. not sure..

I want to make the BES server a backup domain controller as well. the BES server only handles 10 blackberries approximately. its a xeon 2.13 dual core with 2gb of ddr2. I am going to add another 2gb of ram.

So here is the plan. Will this work?
FYI All servers are running Server 2008. Current BB server is 32bit becasue it is also a print server.

I want to install BES on their current domain controller. Much more powerful server. Dual Quad core, 6gb ram I believe.
Then I want to move the users to this new server through the BlackBerry Administration Service.
Next, uninstall BES from this current server. upgrade ram, probably reinstall OS. Make BB server a backup domain controller. Install BES back onto that server, then move the users back.

Should this work?

Any issues I may run into?

How can I experiment with doing a "distributed installation" where I try leaving the Attachment service on a different server to see if that helps?

What directories should I exclude from the antivirus software to minimize issues?
