Dear all i have serious problem with my mail server ( domain controller) win 2003 r2 32 bit
i have three driver raid 5 and one nornmal drive. i noticed that the seconned drive red may be due to dust or some thing but the server was working then the first drive become red then i shut down and remove hard drives and return it back again it shows that seconned hard drive to be replaced then it asks some option accept data loss and continue i think i choosed that one but till now it didnt rebuild the drive when i run smartdrive it shows it building but it didnt built any thing now the replaced hard drive just blimking green when i start the server any help regarding that

What kind of RAID do you use, software (Windows 2003 built-in) or hardware (RAID controller in your server)?
If you can still boot the server, run symantec besr to a nas drive, take an image of your server then format, reinstall and restore
ASKER
well in fact i cannot boot the server the replaced hard drive goes for to option either to press f1 rebuild the drive or f2 continue without rebuilding
the raid is hardware as long am using dl 380 g3 server with win 2003 r2
smart array used if i choosed f1 it keeps rebooting
when i run smart disk it shows in the diagonistic drive needs rebuild

OK, what happens if you insert that broken hard drive and boot server? Is it possible to run it? Do you have a spare hard drive with the same capacity?
ASKER
well i have spare hard disk
and i tried to return back the old hard disk but stil rebooting with note auto recovery started
then it goes to windows and then starting windows then buildin active directory in... then restart again
if i put new hard disk the same
the hard disk start blinking green continously

You can find error codes here
http://docs.hp.com/en/J6369-90075/apcs01.html
but 1778 is nothing wrong :/
Let's wait a little bit more, ok?

in fact i checked out after cleaning the hard drive it shows only one hard drive is failed although at the begenning two show red but i cleaned the hard drive when i check from f8 the status of drives it show two ok and one replacement.
but it shows always when restart that error 1778 and then goes to windows and restart i tried to repair windows it didnt work ofcourse, but how to get the system state back up and exchange backup from the failed and broken raid 5.

in fact i found this comment on similar problem but i didnt understand well
1.remove all drives
2.start server up, clear the controller setup
3.power host down, insert drives as they were
4.power host up, go into controller bios
5.create a new raid5 exactly the way the old one was
*make sure you do not reinitialise the new raid array!
6.mark the failed drive as offline
7.boot
This should take you into a booting degraded raid array. From here on you can replace the failed drive and assign the ew drive as hotspare, so it can rebuild the array
how to clear controller setup and how to be sure of not initilizing the raid array and how to mark the failed drive as offline

If two drives are down at a moment the is no longer working.
You can try to use that solution, but i´m afraid it wont work.
You need to destroy the raid and rebuild a new one exactly as the older one was.

any advice for the fresh installation , what about the entries in the main dc for the same server and about other sites that was connected to
I've never had to reinstall a DC and "teach" the other computers that the new one is the real replacement DC instead of a rogue forgery. I've seen write-ups before on how to do it, but best thing is to log another question in an appropriate group in EE. Maybe somebody has a full step-by-step guide on what to do.

in fact the answer was a cumulative of all and in fact it wasnt the solution for the problem but it describe the problem and what happen
thanks every body and i will post a new question for the case i have now

Without specialized software to run XOR checks and figure out how bad it is, then it is just a guess.
If you have a backup, restore. If you don't, then you better have a few thousand dollars to spend for a recovery (which will still only be partial).
Sorry.
