Author  Topic  adithya Starting Member 1 Post Posted - 2007-01-09 : 16:01:25 Basically the error that I am getting is in our test automation when running as non-admin on the box (regular user). We use .Net C# SQLConnection class to connect to SQL express 2005 impersonating with admin credentials. After getting the connection we try to execute a select command and it some time fails with following error: A transport-level error has occurred when receiving results from the server. (provider: TCP Provider, error: 0 - The handle is invalid.) at System.Data.SqlClient.SqlConnection.OnError(SqlException exception, Boolean breakConnection) at System.Data.SqlClient.SqlInternalConnection.OnError(SqlException exception, Boolean breakConnection) at System.Data.SqlClient.TdsParser.ThrowExceptionAndWarning(TdsParserStateObject stateObj) at System.Data.SqlClient.TdsParserStateObject.ReadSniError(TdsParserStateObject stateObj, UInt32 error) at System.Data.SqlClient.TdsParserStateObject.ReadSni(DbAsyncResult asyncResult, TdsParserStateObject stateObj) at System.Data.SqlClient.TdsParserStateObject.ReadPacket(Int32 bytesExpected) at System.Data.SqlClient.TdsParserStateObject.ReadBuffer() at System.Data.SqlClient.TdsParserStateObject.ReadByte() at System.Data.SqlClient.TdsParser.Run(RunBehavior runBehavior, SqlCommand cmdHandler, SqlDataReader dataStream, BulkCopySimpleResultSet bulkCopyHandler, TdsParserStateObject stateObj) at System.Data.SqlClient.SqlDataReader.ConsumeMetaData() at System.Data.SqlClient.SqlDataReader.get_MetaData() at System.Data.SqlClient.SqlCommand.FinishExecuteReader(SqlDataReader ds, RunBehavior runBehavior, String resetOptionsString) at System.Data.SqlClient.SqlCommand.RunExecuteReaderTds(CommandBehavior cmdBehavior, RunBehavior runBehavior, Boolean returnStream, Boolean async) at System.Data.SqlClient.SqlCommand.RunExecuteReader(CommandBehavior cmdBehavior, RunBehavior runBehavior, Boolean returnStream, String method, DbAsyncResult result) at System.Data.SqlClient.SqlCommand.RunExecuteReader(CommandBehavior cmdBehavior, RunBehavior runBehavior, Boolean returnStream, String method) at System.Data.SqlClient.SqlCommand.ExecuteReader(CommandBehavior behavior, String method) at System.Data.SqlClient.SqlCommand.ExecuteReader() This happen only in the non-admin scenario mentioned above. Any idea what is triggering this? Thanks Adithya
