Hi,<br />
<br />
You can use Exchange Troubleshooting assistant to see what is the problem, here are some links that can help you with this tool:<br />

The STORE.EXE will chew through RAM yes, and re-allocate it as required.<br />
However, due to the low price on RAM nowa days, I recommend an additional 4GB, and try ensure you log files are on a seperate drive to the Databases and that you perform a backup and log flush daily.<br />

<div>
Most of the time I see this caused by third party applications. Store.exe is using the RAM, but AV or something else Exchange integrated doesn't allow the RAM to be released back to the system when asked for. <br />

Thanks for the comments guys<br />
<br />
will check out the troubleshooting tool and report back<br />
<br />
first instinct is just to chuck more ram in there but still at cost,<br />
My old p3 exchange 2000 server ran this same load fine. <br />
<br />
AV could be an option, i got kaspersky on there, we have other<br />
measure in place so can safely turn that off for a few hours,<br />
<br />
cheers

Hi again<br />
<br />
Right this morning have disable my on access for both the database files and exchange data drives, hopefully that should sort everything out, also added these to the &quot;trusted zone&quot; on my av<br />
<br />
see how it goes, will report back, <br />
<br />
has anyone got any thoughts on weather this would work<br />

<div>
Well the antivirus has been disabled for the last 24hrs and still no improvement
</div>


<div>
Disabled or removed? <br />
What else is on the machine?<br />
<br />
-M
</div>


<div>
All process's and files for the AV were added to the &quot;trusted&quot; zone, <br />
<br />
I have also just added another 4gb of ram and still no joy. <br />
<br />
My main concern when i run the exchange troubleshooting assistant is on fatal error which is:<br />
<br />
error accessing the &quot;MSExchangeDSaccess Domain Controllers&quot; performance counters<br />
<br />
I also have unusually high rpc activity detected, most of my clients are still on outlook 2000, could this be the issue?
</div>


<div>
I think I really need a copy of Exmon that works on exchange 2007, apparently one exists however you have to open a support call with ms which costs £200, which is ridiculous!!!<br />
<br />
Anyone know where i can download this??

Hi<br />
<br />
I have 2 newish servers running Windows Server 2008 (64bit) with Exchange 2007 installed. <br />
<br />
The specs are: <br />
<br />
E5420 @ 2.50 x2<br />
4GB RAM<br />
Various hard drives at RAID5<br />
<br />
However both seem to slow after around 24 to 48hrs after a restart. <br />
<br />
Looking at resource monitor i notice 3.8GB of the 4GB of RAM is being used with the majority being taken up by STORE.exe. I have read the mass of pages that tell me store is designed to work this way and it should reallocated RAM as it is required by other process's on the server. <br />
<br />
Still, users will notice mapped network drives becoming slow after this period, as well as emails taking longer to open and generally poor performance all round. <br />
<br />
Is there just not enough RAM there, I have 2 exchange databases (on each server), which come to a total of 30GB, There are around 30users on each server accessing via the mapped network drives. Around 40 exchange mailboxes on each server. <br />
<br />
Any ideas?<br />
<br />

Store.exe using all my RAM, causing slow performance...
