DAgent 6.9.430 and Windows 7 Forcing DNS Entries

I recently reported to Symantec a problem with Dagent 6.9.430 and Windows 7 when utilizing the "configure" task. As you know DAgent was built for Vista and naturally there will be growing pains when migrating a tool to a newer release of an OS.

Our hardware independent image loads and maintains all of the native settings we have set by design. It is a thin image and has only minor setting modifications. We did however recently discover that the DNS settings for our Windows 7 computers were automatically being forced to alter a setting by DAgent.

By default our image would load and the following setting for DNS properties were as follows:

Network Properties > Local Area Connection > Properties > Advanced Settings > Internet Protocol Version 6 (TCP/IPv6) > Properties > Advanced (DNS Tab):

The radial button for Append primary and connection specific DNS suffixes is selected and the Append parent suffixes of the primary DNS suffix was checked.

(the same settings are true for Internet Protocol Version 4 (TCP/IPv4) as well.
 
After we use the DS console to either configure the computer to change the name or any other configuration task the settings listed above for IPv4 and IPv6 were forced to modify and automatically changed:

It selects the Append these DNS suffixes (in order): radial button and put a fully qualified domain name in the list.

Ex: Contoso.Contosotechnologies.com in the list of DNS suffixes.

This never happens to Windows XP nor Windows Vista computers when configuring computers with either Aclient (XP) and Dagent (Vista), but always occurs with Dagent (Windows 7).

Symantec supports was able to confirm this problem with me and is aware of it (I cannot tell you if or when a solution will be released) but there is a workaround we have implemented for this:

When configuring a Windows 7 computer with Dagent 6.9.430:

1) On the TCP/IP section of the configuration GUI screen - replace the entry in the DNS connection suffix field with just a space (hit the space key)
2) Select the Advanced button on the same GUI screen and select the DNS tab > Remove any Domain suffixes found in the Append these DNS suffixes (in order): field

Click OK and finish the configuration Task.

If you have a Deployment task that adds computers and laptops to a particular Domain and OU you will need to modify that job as well.

Hope this was helpful.
