Dell Warranty Script Updated
5/11/2011 Update: http://myitforum.com/cs2/blogs/skeiffer/archive/2011/05/11/dell-warranty-info.aspx
Todd Miller noticed that the Dell Warranty Script (http://myitforum.com/cs2/blogs/skissinger/archive/2008/12/03/dell-warranty-info-hardware-inventory-extension.aspx) was no longer reliably returning the results expected. After some testing, we think we have the script updated correctly. The updated script is in the link above.
As always, the Dell Warranty script, used to locally populate a WMI namespace for later hinv/custom mof retrieval, is dependent upon two main criteria: 1) that your computers have the rights to query a web page on the internet (not all companies' proxies or firewalls permit this), and 2) that Dell does not change the format of the returned information when using a specifically formatted web page request.
Since I think this is the 3rd or 4th time the Configmgr community has updated the script, I think we can safely presume that every few months, Dell does change the format of the returned information. So please keep in mind that this script + mof edit are intended as a useful guide, but are not meant to be the correct official source for warranty information in your company. The correct channel for determining Warranty information is the channel(s) you have always used: communicating with your Dell service representative for your organization and working with them to get official counts and information.
