Whaddya know how to Use of the /3GB switch in Exchange Server 2003 on a Windows Server 2003-based system

A friend of mine is asking on how to use the /3GB parameters to fully utilize the memory management of your Windows Server 2003 to support Exchange Server 2003. It's been a while since my last setup and configuration of Exchange Server 2003 (maybe because I am managing Exchange Server 2007, by the way SP1 for Exchange Server 2007 is out).

When I need to get some information related to Microsoft Exchange Server, I always search it first through http://support.microsoft.com website. Yes not Google search. You will get 95% relevant information than searching to Google. Well it's a Microsoft product anyway.

Here's the information I've found on how you can configure your Windows Server 2003 to add the /3GB and /USERVA=3030 parameters.

"After you have installed Windows Server 2003, modify the Boot.ini file, and then add the /3GB and the /USERVA=3030 parameters to the startup line" (2009, Support.Microsoft.com)
For example:
[Boot Loader]
Timeout=30
Default=multi(0)disk(0)rdisk(0)partition(2)\WINNT

[Operating Systems]
multi(0)disk(0)rdisk(0)partition(2)\WINNT="Microsoft Windows Server 2003" /fastdetect /3GB /USERVA=3030

There you go, reset your server and run TASKMGR to see improvement to your Exchange Server 2003. Read here for more information.

Frequent Account Lockout in Active Directory

I have a user in Windows Pro 7, and Windows Server 2003 environment that is frequently account locked out. I tried many different scenarios to resolve this account lockout issue, from resetting his password, changing a new password, remove and re-join the domain, rebooting the workstation and active directory servers.

I tried to use the command prompt utility to run "rundll32.exe keymgrdll, KRShowKeyMgr" (case sensitive) to delete the account in Windows 7 password cache, and still no luck.

Still searching for answer ... Let me know if you encounter a similar issue in Windows Pro 7 and Windows Server 2003.
