JSI Tip 9382. A BizTalk Server Host instance fails and posts 'General Network' errors to the Application event log on Windows Server 2003 SP1?

The subject behavior can occur under heavy load, because the high activity is incorrectly identified as a denial of service attack.

To workaround this behavior, turn off the new denial of service detection:

1. Open a CMD.EXE window.

2. Type the following command and press Enter:

REG ADD HKLMSYSTEMCurrentControlSetServicesTcpipParameters /V SynAttackProtect /T REG_DORD /F /D 0

3. Restart the server that is running SQL Server.
