Problems with forward DNS-zone in server 2008.

[sch]

My company is currently running a MS server 2003 domain, but we are in the process of getting ready to raise the domain to 2008.

 

Because of this, we went ahead and installed new domain controllers with 2008 and transferred the FSMO-roles to them. All our DNS-zones are AD-intergrated, except one. Now, before the upgrade, the zone replicated fine between the servers. From 1 master, to 3 secondary servers.

 

But after we changed to 2008, and removed the old 2003 servers, i haven't been able to get the replication going again. It's running fine on the master server, but on the secondary ones, it keeps crashing all the time, and then i have to go in manually to reload the zone again.

 

I have set zone transfer to "any server" on the master server, and notify to the selected secondary servers who also holds the zone. The reason for zone transfer to "any" server is simply that it just won't work without. If i minimize it to the servers i want, i can't even get the zone running at all on the secondary servers.

 

The DNS-log and debugging log for the DNS-servers tell me nothing. The whole problem is quite frustrating, because i constantly have to check manually if the zone has crashed on any of the 4 secondary servers, and i never know if i have a failover for that zone or not.

 

Does anyone know what is causing this, or what i might have done wrong?

it keeps crashing all the time

 

What do you mean by this?

 

Have you set it to replicate to all DNS servers in the domain or the forst?

By that i mean i randomly get an error when selecting the zone:"Zone not loaded by DNS server. The DNS server encountered a problem while attempting to load the zone. The transfer of zone data from the master server failed.

 

Correct the problem then either press F5, or in the Action menu, click Refresh."

 

After i reload the zone manually, it stays ok for a while, then goes down again like explained above.

 

The zone is set to replicate to 4 spesified servers within the domain only.

 

Now, obviously it is something between the master server and the secondary servers, but i just can't find out what it is.
