Tech Tip: Remove Outlook Express/Secure Win2K file systems with RAID

Learn how to remove Outlook Express and secure file systems with RAID.

Windows 2000 Professional: Manually remove Outlook Express

You can add or remove many of the applications included with Windows 2000 Professional via Control Panel. However, you can't remove Outlook Express using this method. If you don't use Outlook Express or you need to reinstall it, you can manually remove it.

This process isn't complicated, but it does involve several steps. Start by setting folder options to display both hidden files and protected operating system files. After making sure you've backed up any Outlook Express data if necessary, rename the following folders, adding _old at the end of each:

C:\Program Files\Common Files\Microsoft Shared\Stationery
C:\Documents and Settings\username\Application Data\Identities
C:\Documents and Settings\username\Local Settings\Application Data\Identities
C:\Documents and Settings\username\Application Data\Microsoft\Address Book
C:\Documents and Settings\username\Local Settings\Application Data\Address Book

Next, open the Registry Editor, and delete the following keys:

HKEY_LOCAL_MACHINE\Software\Microsoft\Outlook Express
HKEY_LOCAL_MACHINE\Software\Microsoft\WAB
HKEY_CURRENT_USER\Identities
HKEY_CURRENT_USER\Software\Microsoft\Outlook Express
HKEY_CURRENT_USER\Software\Microsoft\WAB
HKEY_LOCAL_MACHINE \Software\Microsoft\Active Setup\Installed Components\{44BBA840-CC51-11CF-AAFA-00AA00B6015C}
HKEY_LOCAL_MACHINE \Software\Microsoft\Active Setup\Installed Components\{7790769C-0471-11D2-AF11-00C04FA35D02}

Finally, search for and rename the following files. Note that each file resides in two locations. Rename both copies, adding _old to the end of each.

Inetcomm.dll
Msoeacct.dll
Msoert2.dll
Msoe.dll
Msoeres.dll
Msimn.exe
Oeimport.dll
Oemiglib.dll
Oemig50.exe
Setup50.exe
Wab.exe
Wabfind.dll
Wabimp.dll
Wabmig.exe
Csapi3t1.dll
Directdb.dll
Wab32.dll
Wab32res.dll

Windows will display a file protection warning. Click Cancel when prompted to enter the Windows 2000 CD, and click Yes when Windows asks if you want to keep the unrecognized file versions. Restart the computer after you've renamed the files.

Note: Editing the registry is risky, so be sure you have a verified backup before saving any changes.

Windows 2000 Server: Secure file systems with RAID

RAID provides a mechanism for fault tolerance and redundancy in file systems. Windows 2000 Server supports three RAID levels: 0, 1, and 5.

RAID 0 writes data across all volumes in the array to improve performance. RAID 0 volumes, also called striped volumes, allow the reading and writing of data to multiple disks in the array, which improves overall disk throughput.

However, RAID 0 volumes don't provide any redundancy. If a volume in the stripe set fails, the entire array is lost.

RAID 1 comprises two identical copies of a volume, each residing on a separate dynamic disk. This mirrored volume set provides redundancy in the event that one disk fails; the second disk in the set can continue to function until you replace the faulty disk and restore the mirror.

RAID 5 is a striped set with parity. It writes data across all volumes in the set (striped) as in a RAID 0 array, but it adds parity data to enable Windows to reconstruct the data if a disk fails.

A RAID 5 array requires at least three identical disks. The result is a performance improvement from striping and redundancy from the added parity data.

You can create each of these types of volumes on a Windows 2000 server using the Disk Management branch of the Computer Management console.

The RAID capabilities built into Windows 2000 can be useful for improving performance and adding redundancy in a variety of situations. If you require even better performance or additional RAID features, consider one of the many hardware-based RAID solutions available for the Windows platform.
