have this random communication link failure problem. It seems to happen completely randomly. [Microsoft][ODBC SQL Server Driver]Communication link failure Anyone have any suggestions on what causes this? The server is completely patched with all drivers up to date. Specs: Server 2003, SQL 2005 SP3 9.00.4035 Standard Edition Monday, communication link failure sql server 2008 February 15, 2010 9:50 PM Reply | Quote Answers 0 Sign in to vote Hi homeguards,"Communication link failure” means that an existing ODBC connection was closed, and we tried to use that connection. Usually an existing connection being dropped is either a failure of a client to sent packets to keep the connection open, or intermediate network hardware dropping a connection, or SQL Server having a problem.To determine who is dropping the connection, we needed simultaneous network captures on both the client and SQL Server, for the few moment before the issue, and during the issue.Generally, we can try these things to solve the issue:1.Disable TCP Chimney and other Scalable Network Features per http://support.microsoft.com/kb/951037/en-us2.Enable the SQL Server port in Firewall.3.Update the Network Interface Care driver.If there is anything unclear, pleaes feel free to ask.Thanks,Jin ChenJin Chen - MSFT Marked as a

Any one have any suggestions??? I am trying to open linked tables in Access 2003 on http://www.dbforums.com/showthread.php?985897-ODBC-call-failed-communication-link-failure Windows XP (Jet 4.0 Service Pack 8 is installed). The tables reside in a SQL 2000 DB. I can view the details of linked, and I can open some of the tables, but two of the tables are causing problems. When I try to open them, one of the two following messages comes up: "ODBC Call Failed" and then the table opens but all of the cells have #Name? OR "ODBC Call Failed. [Microsoft][ODBC SQL Server Driver] Communication Link Failure (#0)" then when I close that, another box opens saying "Microsoft Office Access can't open the table in Datasheet view" and when I say ok to that, it then closes and just shows the table list. After one of these two tables triggers the Call failure error, then I can no longer open the other tables that were working - they all present the Call failure / communication link failure error. I have to close Access and then go back in to get the other tables to open again. Any suggestions are greatly appreciated. Cheryl Reply With Quote 03-10-04,12:12 #2 rmersch View
