Re: Application Issues with W2K3 SP1 - Networking Timeout??

You'll have to sniff each segment and see if you can find where the problem
is at. You could also follow the vendors suggestion and uninstall SP1.

Hi,

We have a Radiology PACS viewer app that runs just great with W2K3, but
not
with SP1 installed. I have scoured the internet for some answers, and the
only two problems I have seen after SP1 is installed is problems with DCOM
applications, and then TCPIP timeout.

I have gone through and checked for the DCOM problem, but I am pretty sure
it is not that. I am now suspecting network timeout issues. The
appliction
talks HTTP to 1 of 2 IIS web servers through a Summit 5i load balance
switch. These web servers talk to 1 of 5 database servers that send back
xrays/CT's back to the viewer. If I run this client on a non-SP1 server,
the app runs just fine, but as soon as SP1 is installed the requests seem
to
timeout. The request goes out, but nothing makes it way back.

I have tried different network cards, and tried setting the MTU to 1500,
but
nothing works.

The vendor does not really want to help us at all. When they found out we
were trying to get it running on a non-supported platform, they did not
really have any interest in solving the problem.

Does anyone have any ideas what needs to be looked at and where to look
at?

Thanks,

Sean
