packet handling

About this tag
Packet handling in Windows involves processing network data at various levels, from security protocols to system services. Discussions cover vulnerabilities like MS14-066, where specially crafted packets to the Schannel security package could enable remote code execution. The Windows Time service's handling of leap seconds in received packets is also addressed. Performance issues related to packet handling appear in threads about NDIS.SYS consuming high CPU during low network use, often linked to network adapter drivers or system configuration. These topics highlight the importance of proper packet processing for security, time synchronization, and system stability.

    I've been having this problem off and on since I installed W7 that my CPU is spiking during low network use (e.g. 2-3mbit/sec). My setup is W7 (32), Core 2 Quad Q6600 @ 2.4 ghz, Asus P5E-VMDO, 8gb memory. Network Adapter is an embedded Intel 82566DM-2 Gigabit. No other network adapters are...
