Summary
Windows 2003 SP2 x86 becomes too slow in a large network traffic even without InterScan Messaging Security Suite (IMSS) installed. Furthermore, all network-related commands, such as “ipconfig –all”, have no response.

To resolve this, you need to install the latest Windows patch. Contact the hardware vendor to obtain the latest network adapter driver.
