Users Shared Documtents Folder

I have a user on Windows 7 Professional who is having problems with her Documents Folder. We are on a company network and we have her documents pointing to an X: drive that's been created for her on a server. When she logs into her laptop, she has some of her files not available to her. They have an X on them. Once she's been logged in for awhile, she gains access to these files. She is logging in with Cisco anywhere into our network as she works from home.

Any help would be much appreciated.
