    text
    copied!<p>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. </p> <p>If you look in the event log you get the following entry:</p> <pre><code>Exception information: Exception type: FileLoadException Exception message: A strongly-named assembly is required. (Exception from HRESULT: 0x80131044) </code></pre> <p>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. </p> <pre><code>The operation failed. Bind result: hr = 0x80070002. The system cannot find the file specified. Assembly manager loaded from: C:\Windows\Microsoft.NET\Framework\v2.0.50727\mscorwks.dll Running under executable C:\Windows\SysWOW64\inetsrv\w3wp.exe --- A detailed error log follows. === Pre-bind state information === LOG: User = WEBFUND\WF6User LOG: Where-ref bind.

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?</p>
