The following URL is not valid: Error when publishing an InfoPath 2007 form to a SharePoint Library

As per the following link http://joeshepherd.spaces.live.com/blog/cns!9AE2097A4A610B63!137.entry, there is an issue with the System Event Notification Service that will prevent publication of an InfoPath form when there is not network connection (e.g. your Virtual Machine has network connectivity disabled). To fix this issue, disable the System Event notification service while publishing your InfoPath form template.

As per my previous post (http://ddkonline.blogspot.com/2009/02/fix-error-occurred-either-in-outlook-or.html - related to an Outlook issue) you can do this by typing the following at a command prompt:

1. At a command prompt, type "net stop sens" and Enter
2. Publish your InfoPath form
3. Then to restart it, type "net start sens".
