Problem writing file using .Net FileStream.Write to SGI fileserver

[Daniel]

Hello

Since our client upgraded the CIFS fileshare server software (HELIOS
PCShare) on their SGI, our software written using the .Net Framework has
been unable to write to the CIFS shares, throwing a "Not enough storage is
available to process this command." when we attempt a FileStream.Write().
The full stacktrace and other system information is included below.

We have found the following:
(1) A 0 byte file is created in the SGI's CIFS folder.
(2) Using the same .Net software and pointing it at another UNIX machine,
the file is written successfully (isolating the cause as being the SGI
HELIOS upgrade).
(3) Executing a file copy from the Windows Explorer Shell to the SGI box
using the same security context /is/ successfull!

Is the Windows Explorer shell executing different Win32 APIs to the .Net
FileStream.Write() method?

Has anybody at Microsoft or elsewhere come across this before?

Thanks
Daniel

Hello Daniel,

Thanks for your post. According the error message "Not enough storage is
available to process this command", would you please check whether the size
of the uploaded file and make sure that it is not big enough.

Hope this helps.

Some suggestions on debugging this:

1. Capture the network trace between client and server for both failure
(.NET) and success (shell explorer) cases. Compare the traffice and find out
the reasons.

2. My guess is that the SGI server refused client's request. But for the
shell explorer, it may set some additional security settings/credentials
before it issues a "write" request to the server.
