"STOP 0x00000050" Error Message in Rdr.sys with Special Pool Enabled

ID: Q244922

The information in this article applies to:

Microsoft Windows NT Server version 4.0, Terminal Server Edition

SYMPTOMS

You may experience random blue-screen error messages in Windows NT with pool corruption. When you have the Special Pool feature enabled, you may receive the following error message on a blue screen as a result of pool corruption:

Stop 0x00000050 (0xf6eb8000, 0x00000001, 0x00000000, 0x80156000)

CAUSE

This behavior occurs because of a 4-byte overrun in Rdr.sys that is caused when a third-party Server Message Block (SMB) server returns a 36-byte buffer when SMB_QUERY_FILE_BASIC_INFO is sent back to the client. Typically, a 40-byte buffer is returned. This causes the buffer to be off by 4 bytes and Rdr.sys to write past its allocated pool.

RESOLUTION

A supported fix that corrects this problem is now available from Microsoft, but it has not been fully regression tested and should be applied only to systems experiencing this specific problem. If you are not severely affected by this specific problem, Microsoft recommends that you wait for the next Windows NT 4.0 service pack that contains this fix.
