——- Still researching this topic ——
Randomly each day, my computer was making thousands of calls to a couple SharePoint sites. Using Fiddler, I could see that the calls were being made through WebDav.
Then I notice that the first call of the batch was always to this web service:
Googled around and found this post. It’s related to SP2007 but it helped to find the answer.
After reading the post, I opened Word, clicked on File –>Save and Send –> Save to SharePoint. There it was, all of the sites that my computer was reaching out to every day. Taking things one more step deeper, I opened a document library, selected the Library tab in the ribbon, then selected Connect to Office. From there select Manage SharePoint Sites. Displayed was listed the libraries that I had created connections to.
All of the sites that are displayed in the Save to SharePoint section of Office are stored here:
HKEY_CURRENT_USER\Software\Microsoft\Office\14.0\Common\Server Links\Published\My Site\
I deleted the My Site folder, opened Word and all of the sites were cleared out.
Also cleared out the following folder:
Next I need to make sure the folder doesn’t get repopulated with random sites!
