When the Object Manager calls a close procedure and the ObpInitKillMutant is held while handles are being closed in the cleanup process, new processes cannot be created.

Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.
This problem was first corrected in Windows 2000 Service Pack 2.
An application may open a file handle that can be inherited. It then spawns a second application, which inherits the handle. The first application then sends down an I/O request that blocks. While this I/O request is pending, this thread is holding the file object lock. The second application then quits without closing its handle.
Object Manager cleans up the handle table. When it gets to this shared handle, it blocks, waiting for the file object lock. The problem is that it is holding the ObpInitKillMutant. The system's being in this state can allow a User mode application to hang the system. At this point, you cannot start any new applications, including Task Manager, and you cannot quit the first application that is holding the file object lock.
NOTE: A similar issue is present for Windows NT 4.0. For further information on this, see the following:
