IP6 v IP4

HI all,
I have a very frustrating problem with one of my Windows 2008 R2 servers.  Every single time when it is re-booted without fail it will not register an A record for itself in DNS IP6 is fine but not IP4.  I have to manually logon to the box and ipconfig /registerdns then alls fine until the next reboot.

I have tried variouse hacks like disableing IP6 altoghter but it didnt work and tbh should I really have to do this?

I have checked and double checked that all the right tick boxes are ticked.

I have two DHCP servers on my network one is housed on a Windows 2008 R2 and another soon to be decomissioned 2003 box.  I have looked around the internet for a soultion and found many people having the same issue but no resolution.

XP clients are fine it just seems to effect IP6.

Regards

John

having 2 dhcp servers active on the same subnet is a recipe for disaster.  Which dhcp server is causing the problem? which one is it registered in?? This will vary by time.

Best practices suggest using fixed IP address on a server and creating a DNS record manually for it. That is the simple fix.

I'm aware its not best practice to have two dhcp servers on the network however I was in the process to migrating from windows 2003 to 2008.

I'm also aware its not best practice to have servers on DHCP but again this issue came to lighrt as I was testing the server before deployment.  You are correct tho once a static IP was assigned the issue went away.  This is a quick fix but I'm still intrigued that this issue has no resolution I have search the issue and have found quite  a number of people with the same issue I would have thought Microsoft would have rushed a fix for this.  I wonder if this effects Windows 7 PCs.

I will close the call in a few days to see if anyone else has any answers

Cheers
