Enable location roaming

If you use role-based administration:

You must have the Policy setting - updating right to configure an updating policy.
You cannot edit a policy if it is applied outside your active sub-estate.

For more information, see Managing roles and sub-estates.

You should only enable location roaming on groups of machines that frequently move from office to office.

To enable location roaming:

In the Policies pane, double-click Updating. Then double-click the updating policy you want to change.
In the Updating Policy dialog box, on the Primary Server tab, select the Allow location roaming check box.
In the Groups pane, select a group that uses the updating policy you just changed. Right-click and select Comply with, Group updating policy.
Repeat this step for each group that uses this updating policy.

Note: If you later need to revert back to using the primary and secondary update locations specified in the updating policy, disable location roaming.
