Regarding my DNS rebuild (part1)
Regarding my DNS rebuild.
I am writing these notes down now so that I dont forget what I did when I post an update on how my network is behaving (probably in a few weeks time).
My feeling is that our windows network was fine for PC clients but macs, being extremely fussy, didnt like it. I rather suspect the apple have just done some minimal testing as far as integrating into windows environments is concerned and therefor if your network isnt 'just so' then your macs are going to go into a huff, ......did I mention about the hassle with using macs on our expensive and sophisticated network environment - the upshot was that we had to 'dumb-down' our switches in order to accommodate the picky macs with network card drivers that dont conform to internationally recognised networking standards [and Apple think its not their problem].
Anyway this is what I've done to our servers and I am still monitoring the situation, so dont take it as gospel....
Most of the client computers had been switched off over easter so the DNS records would have mostly been stale - the DNS was going to be flushed and rebuilt so it was to our advantage too.
First step make sure all the servers (windows and OS X) are updated with patches, and BACKUP system state.
Second step, refresh my brain on how to configure DNS & DHCP, I'm a great believer on setting things up with the instructions in front of me, then hopefully I wont need to look at for at least a few years.
Third step clear down DNS and de-integrate it from active directory. Then stop the service and delete all traces of DNS in AD or text file.
Fourth, check DHCP, reconfigure if neccessary
Fifth, configure the servers and get them all talking and behaving nicely with one another.
Next, rebuild DNS and replicate across servers, check DNS contains correct records and register any machines with static IPs.
Next get the windows client PCs back onto the network, well logon to an AD account cos you just know they are gonna work
Finally reconfigure each mac client (our machines are dual boot), this is the tedious bit involving coming off the domain, clearing down plists, renaming, rebooting, rejoining domains etc, hoping that things get finally sorted.
some reading (do read them):
How to clear bad information in Active Directory-integrated DNS
How to reinstall a dynamic DNS Active Directory-integrated zone
How to configure DNS dynamic updates in Windows Server 2003
How To Install and Configure a DHCP Server in a Workgroup in Windows Server 2003
there are other articles, you can take days to read, but I'd decided that I was going to rebuild DNS so they were irrelevant to me.
oh I'm too long on my text, read my next post....
