| Hi Jim,
|
| I tried Filemon and managed to catch a few errors, but the problem is
that
| it's very hard to tell the difference between the requests that have
raised
| the error and those that have not.
|
| For each file, the process seems to be that inetinfo reads the file, then
| aspnet_wp tried to find web.configs in the directory if it is new, then
tries
| to read the requested file (with far fewer events logged than for a
| successful file). I am connecting to the virtual directory using the
same
| domain account that aspnet runs under.
|
| Almost all of the requests for the directories are successful. There are
| two problems (pasted below) the first happens several times, the second
| (which I assume is the problem) just once:
|
| 9:15:21
| AM aspnet_wp.exe:1584 IRP_MJ_QUERY_INFORMATION
\\server\files\downloads\BWM\20041105 INVALID PARAMETER
FileNetworkOpenInformation
|
| 9:15:21
| AM aspnet_wp.exe:1584 IRP_MJ_DIRECTORY_CONTROL
\\server\files\downloads\BWM\20041105 TOO MANY COMMANDS Change Notify
|
| Could this be due to an incompatibility in the NetApp?
|
| I think I'll just have to try doing a Response.Redirect back to the file
| when I catch these exceptions.
|
| Thanks for your help,
|
| Tim
