When an NT server crashes, a network administrator faces the task of reinstalling software applications, as well as restoring data from backups. Although restoring from backup is reliable, in most cases, the network administrator must still ensure that permissions for files and folders are successfully established.
Most software backup applications normally restore data with the current permissions to file and folders. However there is a way to ensure that permissions are properly restored to the correct files/folders -- save the permission data like your working data. This method -- like performing normal backups -- is a proactive measure. When you do it, you should keep the information stored in a secure place, together with the backup tapes.
Backing up the shares
- Run registry editor (regedt32.exe)
- Select HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesLanmanServerShares
- From the registry menu click the save key
- Save the file to a diskette
Restoring the shares
- Run the registry editor
- Select HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesLanmanServer Shares
- From the registry menu select restore
- Locate the filename on the diskette
- After the restore process reboot
- the server
Note: This procedure only restores domain users permission. Any existing shares will be overwritten.
For the restoration process to work, the folders must be the same drive as with the previous installation. This procedure can also be used when performing a migration from Windows NT to Windows 2000.
