Having trouble saving word documents to a network drive

I am having an issue on a machine that is running windows 7 and office 2007. This issue started when the machine was updated to windows 7 recently from windows xp.

I am opening an Excel spreadsheet from Microsoft Frontpage in our development enviroment. If I attempt to save the file again it tells me "document not saved". I get similar messages in the other office products. I dont believe this is a permissions issue because we have rights for everything on these drives. I cant find much info about this online.

Thanks

Your probably correct that its a permission issue. What type of file sharing are you using?

I meant that the permissions are all correct.

what type of file sharing are you using?

are the files marked as read-only on the server?

Im not a networking expert so im not sure what type of file sharing. The file is located on a the web server for our development site and I access it through frontpage. I also have a network drive mapped for the development site. I CAN save in the mapped network drive in windows explorer. My issue is when I open the file from frontpage 2003 and edit it and attempt to save.

The files are not marked as read only.

Another thing to keep in mind is that this started when the machine was updated to Windows 7 from Windows XP. Another user that is responsible for updating these files is still using XP and it works fine for her.
