A Stop 0x50 error may occurs in Partmgr.sys after unplugging a network cable in Windows Server 2003
After disconnecting a network cable from a network adapter in Windows Server 2003, you may see the following bluescreen:
STOP 0x00000050 (0x00000008, 0x00000000, 0xf74c88cc, 0x00000000)
Note: The address shown in the third argument above may change.
This is a rare timing issue that can occur when disconnecting a network cable from a network adapter while the server is under heavy stress. Having disk performance counters enabled in Performance Monitor may increase the chances of the bluescreen occurring. If you encounter this bluescreen, try disabling disk performance counters in Performance Monitor and do not disconnect the network cable while the server is powered on.
