For the last couple of months we have been plagued by NT machines not booting up because of NTLDR missing. We get anywhere between 5 nad 15 NT machines fail every day due to this problem. Replacing the ntldr does not work as this is not the only file that is missing from the affected machines. It is obvious that there are other system files missing and we ofeten have to reinstall the o/s and all software. The only logical explaination is a virus but we have our antivirus protection up to date and I haven't come across a virus that causes this type of problem on such a large scale. This problem has also affected machines that are only used as print servers and have no applications or email installed on them.
We sometimes have the same pc's go down week after week and there are still a handful of pc's that have never been affected. This problem has been going on for so long now and we are all at our wits end trying to fire fight the issue. No one seems to be able to come up with a solution but we real really need to get it resolved. Please help if you can as we are desperate for any assistance to eradicate this problem.
