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, enter new credentials that will be used to access the server. Change other details, if appropriate.
Note: If your primary update source is a folder on your website and you are using Internet
Information Services (IIS) with anonymous authentication, you will still need to enter
credentials on the Primary Server tab. Use the credentials for
the "initial install source" UNC share, even if you don't need them to access the
webserver. If you leave the Username and
Password fields on the Primary Server
tab blank, you will not be able to protect endpoint computers from the console.
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.
