Symptom: NTLM authentication for a valid user may take a longer period than usual (approximately

two minutes) if the client sends the request when the Content Engine has been idle for 12 or more

hours.

Condition: This problem occurs in the following circumstances:

a. NTLM request authentication is enabled on the Content Engine.

b. The request is sent after the Content Engine has been idle for 12 or more hours.

c. The client machine has some malfunctioning program (for example, spyware or a virus) and is

sending HTTP requests to the Content Engine along with the first request from the browser. The

user agent is named Tioga, and the request is as follows:

GET http://somehostname/Zone-UVWXYZ/config.cfg HTTP/1.0\r\n

Request Method: GET

Accept: */*\r\n

User-Agent: Tioga\r\n

Host: somehostname\r\n

Pragma: no-cache\r\n

where somehostname is a hostname.

The user will be authenticated after waiting approximately two minutes. After reporting a

failure to the browser, the Content Engine uses the same credential and retrieves the group

information for that user from its HTTP authentication cache.

Workaround: On the Content Engine, configure a rule to either reject requests from the user agent

named Tioga, or configure the no-auth rule to bypass authentication for this user agent.

Symptom: The table of contents and the index of the ACNS Content Distribution Manager online

help are not functioning. When you open the online help window, the left pane, which contains the

table of contents and index, appears blank.

Condition: This problem is caused by the Windows Security Update MS05-001. This security patch

prevents the creation of an instance of the HTML Help ActiveX control that is served in HTML

content from outside the Local Machine zone.

Workaround: Because the ACNS Content Distribution Manager is part of your internal network, you

may modify the Windows registryto allow execution of ActiveX controls that are served from within

the intranet zone. For more information on modifying the registry to workaround this issue, refer to

Microsoft Knowledge Base article 892675, which is available at this URL:
