W3wp is a IIS worker process which indicates that webservice is a busy bee.<br />
<br />
What are the specs from this domain controller? Especially memory....

Thanks for the reply. Its a Xeon 2.4 with 16GB memory and has been running perfectly for months as it doesn't do a lot other than exchange and file store

Hi<br />
<br />
That should be enough memory for a not to complicated mail server.<br />
What is there to learn from the events log and from DCDIAG ?

This the only issue it shows<br />

Hi there, we have a SBS 2011 server that keeps freezing. It either comes back on or we cant wait and have to reboot it manually which is not perfect. Once it comes back it shows the winlogon service has stopped but I am sure this is due to no resources available. The only thing that looks od is the w3wp.exe running at 1.4GB<br />
<br />
Any ideas?

Small Business Server (SBS) is a line of server operating systems targeted at small businesses by bundling the operating system with a number of other Microsoft products that would normally need to be purchased or licensed separately. The most notable inclusions are Exchange, SQL Server, SharePoint and ISA/TMG (Microsoft's firewall and proxy server).
