Document not Saved in Excel 2007

I am having an issue with all of my Excel documents saving from the network drive.  Whether I open the document then "save as" 97- 2003 or just do a straight "save" it will always come up as "Document not saved".  I open some Word files and get a different error, "There has been a network or file permission error.  The network connection may be lost (the drive contents here)"  Now I am online and can do emails and open other documents from the network so I know my network connection is not lost.  I work right off the LAN and not wireless.

 I did take the file in both Excel and Word and copy them to the local drive then try the open / save as and it will work great like that no problem.  Although this is a "work around" is there something I am missing?  Our corporation has many new machines running Windows XP Pro along with Office 2007 Pro and this was the first I had seen this problem with.  This is a laptop, but again others work fine ( that I know of)
