Gus,

Please refer to the article below concerning recommended best practices for using dynamic disks with Windows 2000:

329707 Best Practices for Using Dynamic Disks on Windows 2000-Based Computers
http://support.microsoft.com/?id=329707

Apply the Windows 2000 SP4 to the operating system before placing the server in production, then upgrade the first disk to dynamic.
Restart once, then restart again. This step is required. Following the second restart after upgrading the first disk to dynamic disk, create
a small (1GB will do) primary partition on the second disk, assign it an arbitrary drive letter, format it NTFS. Delete the partition on the
second disk. This step created a master boot record on the second disk, which will be available to allow booting using the shadow of the
mirror set if the primary fails, otherwise you'll need to use a fault-tolerant boot disk. The second disk should not have any partitions
defined on it before it is upgraded to dynamic disk and the primary disk's partitions are mirrored to it.

You should make and maintain current an Emergency Repair Disk (backup the registry when creating the ERD), a system state backup, an
Exchange Information Store backup and backups other data regularly to minimize data loss should the server crash even though you have
a fault-tolerant RAID array. RAID arrays do not substitute for backups. I also backup my server's backups to a tape and a portable disk
(yep, 3 backups.)

On an unrelated note, you should configure folder exclusions from Anti-Virus real-time and scheduled scans on the SBS 2000 server per
the 4 articles cited below:

I have a Compaq Evo D310 computer, on wich I installed SBS 2K. After
installing I tryed to upgrade system disk to dynamic disk. At restart the
system won't start, and gave me an error: INNACCESIBLE_BOOT_DEVICE with a
blue screen.

I tryed reinstalling the server and I got the same error when I tryed to
upgrade the disk. It is now useless to say that I lost a lot of data, being
unable to make a mirror.

I am still having this problem. Now I have system disk in Basic mode. I am
affraid to upgrade it again. What should I do to make a mirror on this disk?
