What Does the Error Imply and How Does it Appear?

Regular computer maintenance sessions can keep your gadgets fit and healthy, but some uncertain problems with the programs or network may stop your computing processes. Users may get the error while connecting to SQL Server using TCP/IP protocols. One of the biggest impacts of the same could be that you’ll not be able to connect to the Internet until you resolve the error. The error message may display the following error statements:

  • “TCP_PROV: An existing connection was forcibly closed by the remote host.”
  • "ProviderNum: 7, Error: 10054, ErrorMessage: "TCP Provider: An existing connection was forcibly closed by the remote host ..."
  • “Unhandled Exception: A transport-level error has occurred when sending the request to the server. (provider: TCP Provider, error: 0 - An existing connection was forcibly closed by the remote host.)”

Causes of the Error with Suitable Resolutions

Scenario 1

Users may experience the error when the ‘Client’ is trying to connect with an unsupported/outdated version of the SQL Server Native Client. If it is the case, users should try to update the ‘Client’ computer to the latest/supported server version of the SQL Server Native Client. Updating the server version will make the ‘Client’ compatible with it and helps in resolving the error without seeking the help of a computer support technician.

Scenario 2

If you’re using faulty network hardware, then it may result in dropping portions of the TCP traffic. The dropping portions of the TCP traffic may not allow the network to connect to the ‘Host’ and ‘Client’ properly, resulting in displaying the error code discussed above. To resolve the same, you should install and use strong network monitoring programs that possess capabilities to analyze ACK, TCP SYN, and FIN messages.

Scenario 3

Sometimes, the ‘SynAttackProtect’ settings may also result in dropping connections and leaving users annoyed with the error message mentioned above. If you’re using the Windows Server 2003 Service Pack 1 and later, then you may get the error because the TCP requests arrive faster than SQL Server can service them. Users getting the error because of some problematic ‘SynAttackProtect’ settings can follow these tips to resolve the issue:

Launch the ‘regedit.exe’ utility and add the following registry key:

“HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\

DWORD

SynAttackProtect

00000000”

Important Note: Adding the registry key may expose the server to a denial-of-service attack. Always remember that you should only add the registry value if you have complete understanding of the security risks. Don’t forget to remove the registry value when testing gets completed.
