Win2K3 Integrated Authenticaton and file download issue?


Win2K3 Integrated Authenticaton and file download issue? Dan Marsden
1/31/2007 3:15:01 PM
iis security: We have an issue on a Win2k3 Virtual Server sitting on a VMWARE box with
Integrated Authentication.

When Integrated Auth is turned on, sometime (not always!) large files get a
time-out message when you try to download them. In fact, it even happens
with some smaller files (but inconsistently). But - the weird part is If we
go back to basic authentication, the problem goes away!

We did a Network Trace on what is being transferred and it appeared that the
files *are* being completely downloaded but the client(IE 6) rejects them
with an error message.

Anyone have any ideas?

Thanks!

Client side timeout usually indicates that the client failed to
retrieve the expected number of bytes of response within the client's
alloted time.

If you see evidence with a Network Sniffer that the server transferred
all the bytes it claims to send via Content-Length: response header
(or chunked encoding terminating chunk), then clearly the server met
the contract to the client... why the client times out is a client-
side concern.

Can you reproduce this outside of a Virtual Server within VMWARE (I
think Microsoft only supports running Windows within MS Virtual
Server)?

Can you reproduce this with another browser under Integrated
Authentication?

Thanks David,

We haven't managed to re-produce using a standard install outside VMWARE -
Will ask the team involved to try NTLM with IE7 and FF - it's a hard one to
reproduce all the time because it's intermittent!

any other ideas would be appreciated!

thanks,

Dan
