Screen freeze when running a .net application

[Wei]

Hi,

I have a .net application serves 150 user simultaneously to answer multiple
choice questions on-line. Back end SQL server 2000. After the process
started about 45 minutes, most of the user's screen got freeze. It happened
three times. If 10 to 15 users work on the system for three hours, the
system works fine. Could anyone tell me what can cause the problem and where
I should look into? (including code, SQL server IIS server)

Thanks alot

Hi Wei,

If you are talking about web forms then i suggest you to monitor server
memory usage. This might be the culprit..

Suggest you also check eventlogs for any system errors. Also do see if IE is
fully patched (and is virus free). The code looks fine..

Hope this helps...

Need some help, do post a msg back...

Happy Coding

Hi Vishnu-Chivukula,
There was a system error while the server tried to communicate with the
domain controller when the failure occurred.
There was no error on the SQL server event logs. Server memory usage was
fine.

Thanks
