I have a Windows 2003 network and we are having issues with DNS. I noticed that some host a records were incorrect. I figured out that this was du to the fact that the computer account didn't have rights on the record. This is the case for some of them (haven't gone through all of them because we have over a 1000 pcs).
What i really want to know is why some A host permissions would not be correct. I don't know of any that would have been created manualy. I can unederstand if a computer was reformatted or replaced with the same name and the computer account was deleted and recreated but this would leave the old SID in the permissions. (some have this) But in my case the records have no computer accounts or unknown SID accounts in the permissions just all the other default ones.
I want to make sure this doesn't happen again so i would would like to know what caused this. Any ideas?
Also i would like to correct this wothout having to go through each record individually. Any ideas?
