Using the DRNetConfig Utility for BrightStor Disaster Recovery Option Overview DRNetConfig is a command line utility used to view and modify the TCP/IP configuration information contained in a Machine Specific Floppy generated by BrightStor Disaster Recovery (DR) Option. This utility should be used for remote DR only. This utility is supported on Windows 2000/XP/2003, but not Windows NT. Network configuration information for a Disaster Recovery-protected client machine is contained in a file called W2KTCPIP_DRF. This file is found on the Machine Specific Floppy disk created for the client machine using the Create Boot Kit Wizard as well as in the DR\"client machinename" folder under the BrightStor server home directory. The DRNetConfig utility lets you view and modify this information, giving you additional flexibility when performing a disaster recovery. When to Use the DRNetConfig Utility If changes to the network configuration of the client machine have occurred between the time the W2KTCPIP_DRF file was created (for example, the last full backup) and the time disaster recovery is performed, you can use the DRNetConfig utility to modify the information in the W2KTCPIP_DRF file on the Machine Specific Floppy disk to reflect those changes, and perform the disaster recovery procedure using the changed disk. Example DR stores the MAC address of each adapter, and the IP configuration associated with it, during backup. During restore, DR uses the MAC address of the network adapter to match it to its proper IP configuration stored during the backup. If you have changed the network adapter, the MAC address stored during the backup cannot be found and its corresponding IP configuration may be assigned to the wrong network adapter. This occurs only when there are multiple network adapters in the system and the system is in a static IP environment. Use the DRNetConfig utility to associate the new MAC address of the adapter to the proper IP configuration stored in the W2KTCPIP_DRF file. WARNING! Exercise caution when using this utility. Incorrect information in the W2KTCPIP_DRF file can cause a disaster recovery operation to fail. Using the DRNetConfig Utility Usage: DRNetConfig [-debug] [-dump] {-client clientname|-file filename} Options: -debug Output detailed error information -dump Dump the information in the file to the screen and exit -client clientname View/edit network info for the named client -file filename View/edit network info in the named file Use the -debug switch to instruct the utility to output more detailed information if errors occur. Use the -dump switch to instruct the utility to dump the information in the file to the screen. This switch does not allow you to modify any information. Use the -file switch to specify a file on which to run the utility. This file should always be a W2KTCPIP_DRF file generated by DR. Use the -client switch instead of the -file switch to run the utility on the W2KTCPIP_DRF file contained in the clientname folder under the DR folder under the BrightStor program folder. This switch works only when you run the utility on the BrightStor server used to back up the client.
