Sharepoint list items getting auto modified. All the lists seems modified by a single user. But when checked with the user, he hasn't accessed this list at all. And the modified time stamps are all the same. 100s of items got modified at the same time, which is not possible manually. Any help on this would be really helpful. Thanks
Is a timerjob updating the list items? Usually timerjobs run under the same user as the OWSTimer, but a custom timerjob might open the site using a specific UserToken or something similar...
Or is a feature overwriting/recreating the mentioned items during activation?
Some more information would be useful. Like: is it a productive system or your test environment?
