Hi,

ENV: Windows 2003 Enterprise, Devstudio 2003, .Net framework 1.1, Office
2003 SP1

Since applying the Visual Studio/Office/Windows hotfixes for the JPEG issue,
I am having problems debugging an ASP.Net application.

Visual Studio will hang and consume anywhere from 10% to 90% CPU when
starting debugging of an ASP.Net application. This happens when either
starting the debugger from the IDE or attaching to the w3wp.exe process.
Looking via task manager, the devstudio.exe process is simply spinning CPU
cycles - there is no change in memory usage.

This happens frequently, but intermittently. If it helps, when attaching to
the w3wp.exe process, the point at which devstudio hangs is almost instantly
after I hit "OK" on the "Attach to process" dialog. The IDE does not
refresh after that point or show any indication it has attached
successfully.

The ASP.Net application is running in IIS6 native mode under the default
application pool identity (NETWORK SERVICE).

This has never happened before to me or my colleagues (who haven't applied
the patch yet). Whether it was the JPEG fix or another hotfix, I don't
know. I can't obtain any more hotfixes as the Windows Update web mechanism
hangs at 66% detecting... :)

Do you have any suggestions? Please let me know if you need tracing etc.

Thanks,
Stuart
