This morning I had some troubles with my VPC.. for some weird reason, some webapplications kept prompting to authenticate while working locally on my VPC. But when accessing them remotely I had no problems at all. And I had the same problem last week, but then a simple reboot did the trick.. it didn’t do the trick this morning so I asked in twitter the following question :

quick #SharePoint question : wondering why all of a sudden certain webapps on my vpc keep asking for credentials.. resulting in 401.1's

And literally within minutes I had this result to solve my problem!! ;)

This truly, for me, makes twitter such a powerful social tool to have! So thanks all!
