SYMPTOMSAnti-virus software running on client computers may cause Named Pipes connections to Microsoft SQL Server to fail. The client application may stop responding, take a long time, or sometimes receive error 231, "Connection Busy." On the SQL Server error log, error 17832 "Unable to read login packet" may be logged. Connections to SQL Server using a different network protocol work normally. CAUSE
When the client application requests to open a pipe, and if the anti-virus
software is configured to scan all files, the anti-virus software treats
the pipe as a file, and attempts to scan it. This results in opening the
pipe is a "deny all" mode that prevents the client software from reading or
writing to the pipe while connected to the server. After the pipe is opened
in this mode, the client is not able to send the login packet to the
server. This results in raising error 17832 "Unable to read login packet"
in the SQL Server error log.
