SharePoint 2007 100% CPU Spike – Blue Screen 0x0000001d

Problem

SharePoint 2007 Web Front End (WFE) servers crashing repeatedly.  Environment is SharePoint 2007 (MOSS Enterprise) 64-bit running on Windows Server 2008 Standard.  Server was crashing repeatedly with CPU spiking to 100%, blue screen, and server rebooting itself.  System log showing BugCheck event (1000) entry with code 0x0000001d:

The computer has rebooted from a bugcheck.  The bugcheck was: 0x000000d1 (0xfffff9802ea0ef50, 0x0000000000000002, 0x0000000000000000, 0xfffffa6004e06ed9). A dump was saved in: C:\Windows\MEMORY.DMP.

Resolution

After a lot of troubleshooting, it turns out it was Trend Micro Common Firewall Driver (Trend Micro OfficeScan Client 8.0).  When we disabled the firewall, problem resolved.

    Maybe the firewall driver also uses http.sys?
    Hope it helps someone.
