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
To resolve this problem, obtain the latest service pack for Windows NT Server version 4.0, Terminal Server Edition. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:

STATUS
