I am trying to create a folder on an asset library in SharePoint, while logging from outside the server, and it works fine. Using the same administrator account from inside the server, I was able to create the folder inside the library. How come? Is there any special configuration that needs to be done?
yes, the culprit here is "alternate access mappings" in the central administration. make sure the AAM mappings for the web application/site collection is having correct url pointed in the correct zone with proper bindings.
if there is any problem with the AAM settings, then site collections behave in a very odd way especially for editing.
