Authentication issues on Windows 7 with Internet Explorer 8 (Crystal 2008)


We are in the process of migrating from Windows XP to Windows 7 (with Internet Explorer 8).

I have noticed that a web application which depends on Crystal 2008 is behaving differently in the new environment. For example, when I try to load a report I get this error:

Access to report file denied. Another program may be using it.

I know that this error can be caused by a permissions problem on the Windows temp folder, and I know there are various ways of pinpointing the exact permissions problem and various ways of resolving if that's the case. The fix that worked for us in Windows XP does not seem to work in Windows 7. My gut feeling is that IE is passing credential in some way differently from how it did before.

Since many aspects of security are so different in Windows 7 compared with XP, I was hoping to find some general guidelines from SAP/Crystal re: how to deploy or configure the client/server in this environment.

Are there any general guidelines available?

Thank you for any help... shannon
