Users are able to login and see their network storage using Netstorage.
However, when they try to upload a document through netstorage, we are
receiving an error message that says the following:

The server is temporarily unable to service your request due to
maintenance downtime or capacity problems. Please try again later. ERROR

The download, copy, and move functions are also not working.

Has anyone else run into this type of problem before? Any ideas on what
may be causing this problem?
