I have a windows 2000 server that recently stopped at the BOD screen. The message being displayed is :0X000000D1 IRQL_LESS_OR_EQUAL IDECHNDR.SYS.Is this idechndr.sys file corrupt? I tried going into system recovery and running a few programs, still having the same problem. I was able to get into safe mode to do the search.When I did this the file was in 3 locations. 1 was in system32 dir. and another in the intel app. dir. and they are both the same size. I was not sure what this file is , so I renamed the file in the system32 folder to idechndr.old and re-booted the computer. Now I get a BOD INVALID BOOT DEVICE. I cannot get back into safe mode nor pass this screen. Grant it I'm instructing someone remotely on what to do. They said when they went back into the recovery console and the file renamed is gone. Is it possible to take the other file with the same size and drop in the system32 folder? When I had them do that it said access denied. I hope I explained this correctly. Any help would be appreciated.

you need to get that file back into the system32 directory. it is the driver for the ide bus which is what your disk drives plug into. There are a couple of ways to get it there. one is to mount the disk in another system, log in as administrator and copy the file. The renamed file should still be there, but if it was causing a problem before, it will still cause a problem. BTW, your problem is most likely bad sectors on your disk. get the disk manufacturer's diagnostics and look for bad sectors.
