Office 2003 stops responding when attempting to use save as to a USB drive
Had this happen the other day to a client. When she attempted to use "Save As" to save an updated copy of Word or Excel documents over to her USB drive from her My Documents folder the application would freeze up on her. Thanks to the Microsoft KB article 313937 solution below I removed the mapped drive (that I believe Office was "mapping" for her in the first place without her knowing it) and got her on her way.
To resolve this issue, you must disconnect all network drives that are have any one of the conditions that are stated in the "Cause" section. To do this, follow these steps.
Note Because there are several versions of Microsoft Windows, the following steps may be different on your computer. If they are, see the product documentation to complete these steps.
Right-click My Computer, and then click Disconnect Network Drive.
In the Disconnect Network Drive dialog box, click the letter of the drive that you want to disconnect, and then click OK.
Repeat steps 1 and 2 until all offline network drives are disconnected. If you are not sure about a particular drive, follow these steps:
Click Start, and then click Run.
In the Open box, type the following, and then press ENTER\\computer name\share name
where computer name is the name of the server that is sharing the resource, and share name is the name of the shared resource that you want to use.
If the resource is not available, you receive an error message that is similar to the following:
The network name cannot be found.
