Our asp.net web servers are giving occasional binding problems which result in a page not being displayed to the end user. Pressing refresh usually works.
If you look in the event log you get the following entry:
Exception information:
Exception type: FileLoadException
Exception message: A strongly-named assembly is required. (Exception from HRESULT: 0x80131044)
Our assembly does have a strong name, however given that this works 99.9% of the time I don't see this as the problem. I have turned on fusion binding logging and when the error occurs we get a binding log file.
The operation failed.
Bind result: hr = 0x80070002. The system cannot find the file specified.

I have copied depends.exe on the server and run that. It gives two files not found: GPSVC.DLL and IESHIMS.DLL. But can that be the problem? Given that most pages are displayed correctly shouldn't it always not work if these files are missing?
