SYMPTOMS
Your domain master browser (generally a primary domain controller) may stop responding and you may receive a "Stop OxA in Netbt.sys" error message on a blue screen with the following parameters: 0x000000fc, 0x00000002, 0x00000000, 0xfc7ac47a.

NOTE: The fourth parameter may vary, but the error is in the Netbt.sys driver address space.



CAUSE
This behavior occurs if the master browser receives a broadcast packet with a source address of 0.0.0.0. When the master browser attempts to respond to the broadcast packet, a structure used by NetBT is not filled out correctly.
