192.168.100.1XX , and press Enter . (If you had multiple DNS servers that should get a copy
of the conditional forwarder record, you would click the “Store this conditional forwarder
in Active Directory and replicate it as follows” check box.) Click OK .
If you get an error message that the IP address isn't authoritative for the
zone, wait a few minutes, and then come back to this dialog box. Usually,
the wait clears the error message.
12. To test your forwarder, open a command prompt window, type nslookup w2k8adXX.com ,

Activity 10-7: Testing Access Between Untrusting Forests
Time Required: 10 minutes
Objective: Test access between two forests before creating a trust.
Description: You plan to create a forest trust between w2k8adXX.com and w2k8ad1XX.com,
but first, you want to see what happens when you try to access resources across forests.
1. Log on to Server1XX as Administrator, if necessary.
2. Click Start , type \\ServerXX.w2k8adXX.com in the Start Search text box, and press Enter .
3. You should see a Connect to dialog box asking for your username and password. Type admin-
istrator and Password02 , and then click OK . The logon should be unsuccessful. Without a
trust between the two forests, you can't log on to a domain in the other forest. Click Cancel .
4. Try to access the server again by clicking Start , typing \\ServerXX.w2k8adXX.com in the
Start Search text box, and pressing Enter .
5. In the Connect to dialog box, type w2k8adXX.com\Administrator and Password01 for the
password, and then click OK . You're trying to log on with credentials from the other domain.
This logon should be successful, and a list of shares available on the server should be displayed.
6. When no forest trust exists, you can still access a domain in another forest, but you need the
logon credentials of a user in this domain. The trust precludes the need for credentials in
multiple domains. Close all open windows.
7. Log off both servers to clear the existing connection between the two domains.
Activity 10-8: Creating a Forest Trust
Time Required: 10 minutes

Description: Now that you have DNS set up between the two forests, you can create the forest
trust.
