Hello all.
Short description of the problem:
Server looses records added since last reboot, and server data files are not
updated (data are instead placed in temp files on editing the zone in DNS
manager). The modifications are then lost on reboot of the server.
Long description:
Have a server that has "lost" A pointers two times now.
The first time, I didn't think much of it, but now it happened again.
When checking the DNS in DNS manager, everything looked fine, apart from the
missing A records.
I added the records, and updated the serial for the zones, just to have
fresh (even though it is a master and thus should load the zone from another
server)..
I then looked in the \WINNT\System32\dns directory, and saw something really
strange.
For each zone, that had been updated since the last reboot, there was a
<zone file name>.temp file.
For example: Say that I have a zone called
example.com. The zone file containing the zone data then has the file
name example.com.dns.
If I then add an A record to that zone, and then do a "Update Server Data
Files", the example.com.dns file WILL NOT get updated.
What happens is that a NEW file, called example.com.dns.temp is created,
that looks like the original file, apart from the fact that this file
contains the new A record. The example.com.dns however, does not contain the
new record.
When I then restart the DNS Server service, sure enough, the entries in the
temp files are NOT read, and the records are thus missing from the zone.
I have checked the permissions on the affected zones (at current count there
are 4 temp files in the dns directory), but can't see anything obviously
wrong with them.
Ho hum..
Ehhhh.
The error was so simple it shames me to admit it, but ....
The files were read only. Removed the read only attribute, and everything
went fine.
I wouldn't have posted this since I found the error before doing the post,
except for the fact that I searched MS Technet and KB, as well as Google,
and could find a thing. So I'm posting this so that if another idiot like me
posts the question, you all know what the problem probably is, and can the
help the poor schmuck.
// Cheers.
