SYMPTOMS
Microsoft SQL Server 2000 Service Pack 4 (SP4) stops responding (hangs) after you close a SQL Server connection. This problem occurs on a computer that is running Microsoft Windows Server 2003 Service Pack 1 (SP1). Additionally, SQL Server does not accept any connection requests. When this problem occurs, the following error message may be logged in the SQL Server error log:

server Error: 17883, Severity: 1, State: 0

server Process 2:0 (b58) UMS Context 0x21D17050 appears to be non-yielding on Scheduler 1.



CAUSE
This problem occurs because a Dbnetlib.dll file transfers an invalid socket handle to the closesocket function when you close a SQL Server connection. This invalid socket handle blocks TCP/IP activity. Therefore, SQL Server stops responding and does not accept any connection requests.
