Can anyone tell me how reliable these can be. I am about to make ERD's for a no. of NT4 PC's, just as some kind of failover? How do they work? I heard with the constant registry changes in Windows, it makes the ERD invalid/unreliable...

Any help appreciated...

Well as far as I know with Windows NT, the ERD does copy the current version of the registry every time you update it. Basically how it works is if your NT machine will not boot, or the last known good configuration does not work, you can boot to your Windows NT CD Rom and click the repair option and it will prompt you to insert your ERD disk. From what I understand is that the ERD will go back and check the errors in you system and try to repair them to the date when you made the ERD. I have tried to use the ERD a couple of times and unfortunately it did not help me and of course if you do not keep them up to date just like a backup they will be useless to you. My opinion is that it is a good idea to make them and keep them up to datebecause as always it is better than nothing and it could save you a bit of work in some cases. Also for you info, if you use Windows 2000 the ERD will not restore your registry to the current one; it only restores it to the original date that you installed the operating system. If you use Windows 2000 make sure that you backup the system state also.

Hope this helps you

Hi,
The very first thing i would like to share with u is the entire registry cant accomadate on ERD. It stores only the partial part of registry. Mainly it stores uesrs name with their current passwords, copy of ntldr,Boot.ini, ntdetect.com, ntoskernal.exe, your harddisk's information (Volumes, stripe sets, mirrors) and i mentioned earlier it stors some strings and keys of registry.
To use the ERD you have to have three NT setup disks or Windows NT's CD. To use ERD boot your NT machine with three setup boot foppies or CD
if you are booting through floppy than after inserting 3 rd disk it will ask for repair or new installation. Press R to repair than insert the ERD restore the files which is required.
If you are booting with CD than keep your eyes on repair or new installtion screen than follow the same which i mentioned earlier.

Thanx & Regards
Abhinav
