Mirrored drives show up as seperate drives

Archived from groups: microsoft.public.win2000.general (More info?)

Hi Brad,
It seems that you installed roll up update pack 1 for windows 2000 and it
could not update the mountmgr.sys file. Go to
regedit->hkey_local_machine\software\microsoft\windows nt\current
version\winlogon. Change the value data field to "userinit.exe". Go to
Hkey_local_machine\system\mounteddevices. Backup the whole key and then
delete it. Reboot the machine and see if the problem still prevails. In case
the problem still prevails, go to c:\winnt\system32\drivers and rename
mountmgr.sys to mountmgr.old. Go to c:\winnt\$NTUpdateRollupPackUninstall$
and copy mountmgr.sys to c:\winnt\system32\drivers. Reboot the server. If the
problem still persists, redo the first two registry changes(mounteddevices
and userinit) and reboot. I hope this should solve the issue.
