2005-08-09 20:30:58.021 UTC Warning wsusservice.156 SusEventDispatcher.CheckSelfUpdateTree Retried 3 times but still received error when checking for SelfUpdate Tree. Error: System.Net.WebException: The remote server returned an error: (403) Forbidden. at System.Net.HttpWebRequest.CheckFinalStatus at System.Net.HttpWebRequest.EndGetResponse(IAsyncResult asyncResult) at System.Net.HttpWebRequest.GetResponse at Microsoft.UpdateServices.Internal.SusEventDispatcher.CheckSelfUpdateTree





CAUSE
This problem occurs because the directory security settings for the WSUS server default Web site contain an IP address restriction. This restriction denies the server's IP address access to the WSUS Web site.



RESOLUTION
To resolve this problem, remove the IP address restriction. To do this, follow these steps:
 * 1) Click Start, click Run, type inetmgr, and then click OK.
 * 2) In the left pane, expand  , and then expand Web Sites.
 * 3) Right-click the WSUS Administration Web site, and then click Properties.
 * 4) Click the Directory Security tab, and then click Edit in the IP address and domain name restrictions area.
 * 5) Click Granted access, and then click OK two times.
