How to implement RAID 5 and RAID 1 with NT Server

Ftape configuration

Believe it or not, we have been struggling for almost four years to get our tape drive to work. We originally had an FC-20 with a 768 meg native 3020 Colorado tape drive. By the time the kernel and ftape had caught up to our model, we had replaced it with an Iomega Ditto Max […]

Scheduling backup of directories with tar and cron:

To copy directory /home/myhome/myimportantfiles to /share/myhome/myimportantfiles: cd /home/myhome/myimportantfiles tar -cvf – . | tar -C /share/myhome/myimportantfiles/ -xv To schedule this to happen every day at 1am: crontab -e vi will run.

Simple multi-tape backup with tar / Standby File/Print Server

Using Last Known Good Configuration To Restore an NT System

In this article we used the Windows 2000 recovery console to fix the filesystem on an NT server. Let’s use the recovery console to make a BSOD. We’ll just disable a required boot service: Let’s reboot: Nice!! That is what we wanted. Now, we could boot again and fix with the recovery console: That works […]

Creating an NT Emergency Repair Disk

Rdisk is used to recover your system from boot problems, registry problems, or OS corruption. Run rdisk by start->run->rdisk. You can specify /s if you wish to restore your security permissions. Rdisk is a little misleading. You might assume that simply pushing the Create Repair Disk button would work, but it doesn’t. Make sure you […]

Recovering an NT System With an Emergency Repair Disk

To use the Emergency Repair Disk we created in this article, you need to boot with the three NT setup disks that can be created by running winnt32: If you don’t have an NT box, you can use the NT distribution cd from MS-DOS or a Windows 95/98 command prompt and run winnt /ox. Boot […]
