trust relationship problem

[sguay]

Hi,

 

sorry for my english i'm french:

For my certification for w2k8 Active Directory, I try to make a trust between 2 domains. (contoso & tailspintoys).

 

there is the configuration I use:

 

1x DC domain name: contoso.com

ip: 10.0.0.11, subnet: 255.255.255.0, dns address: 10.0.0.11

 

in my DNS i did a flz with tailspintoys.com

ip address: 10.0.0.111

 

the other configuration for the other DC

 

ip: 10.0.0.111 sub: 255.255.255.0 , dns adress

domain name: tailspintoys.com

 

In the DNS i made a a Contional Forwarders

contoso.com with ip : 10.0.0.11

 

From my DC #1, I ping 10.0.0.111 (DC #2) and vice and versa all the ping works fine.

 

From the DC #2 (10.0.0.111)

I open the properties of the domain to make the trust:

 

Trust Name: contoso.com

 

Trust Type: External Trust

 

One-Way : outgoing

 

This domain only

 

Domain-wide authentication

 

Make a strong PW

 

I confirm the configuration of my trust

 

 

click next and I receive the following message:

 

New trust Wizard (Title of the boxe)

 

Cannot Continue

The trust relationship cannot be created because the following error occured:

 

The operation failed, the error is: This operation cannont be performed on the current domain.

 

then I click finish and the boxe close.

 

maybe someone can help me.

 

Regard

Sguay
