I have some problems with a Windows XP SP3 machine using Excel 2010 and trying to open documents on a WSS 3.0 site through IE 8. The computer is not part of the domain.
The problem is that i have multiple users accessing documents on sharepoint using this machine and different credentials. In normal cases Excel always asks for them when opening the documents but now it seems stuck on user X.
It doesn't matter which users i'm logged into the sharepoint, excel always opens the document as X and never requests credentials.
Do you have any idea on how i can "reset" this behavior or if there is other possible errors?
