I have a problem of SQL connection between two servers. One of the servers where the site code is stored is a Windows Server 2008 and my database is on a Windows Server 2003.
Here is a part of my code :
Set Conn = Server.CreateObject("ADODB.Connection")
ConnStr = "Provider=SQLOLEDB; Data Source=10.0.0.17; Initial Catalog=******;UID=*******;Pwd=********%"
Conn.open ConnStr
Microsoft OLE DB Provider for SQL Server erreur '80004005'
[DBNETLIB][ConnectionOpen (SECDoClientHandshake()).] SSL security error.
So I saw on the internet people talking about enabling TLS 1.0 on my server and that's what I did on both.
Here is what I have in both my client and server registers
But even after that I still have the same mistake.
Could someone please help me
Someone turned off TLS 1.0 support on your database server - thinking that it would improve security.
The October 2021 update of Windows 10 finally updated the SQLOLEDB driver to support TLS 1.2.
Otherwise you'll have to switch the currently supported MSOLEDBSQL driver. It's the only officially supported SQL Server OLEDB since SQL Server 2012, and it supports TLS 1.2.

I've moved a legacy Classic asp app to Windows server 2016
in large part to resolve TLS 1.0 browser issues. The website works just like it should except for one problem. Updating a DB record fails.
I've set up syswow64 DNS and used a 32 bit Oracle 11g express install on the webserver to talk with the Oracle 11g standard DB. Everything seems to be fine with the application except when updating a sequence table. The code worked fine previously on windows server 2008.
rs.open sql, cn, adOpenDynamic, adLockPessimistic, adCmdText
If CheckNativeError(cn, SQL, Current_Sub_name) then
fGet_Next_SEQ_ID = ""
exit function
END IF
Opening and reading the recorset works and now need to update the
rs("NEXT_SEQ") = NEXT_SEQ (next seq = 222250)
rs.Update
Receives the following error.
Microsoft OLE DB Provider for ODBC Drivers error '80004005'
[Microsoft][ODBC driver for Oracle]General error
I'm thinking it is unable to update possibly by a driver issue involving a TLS 1.2 issue but I cannot find the answer why or what to do about it. Other settings for the website are correct, enable 32-bit code.. app pool, etc.
32 bit Driver used: Microsoft ODBC for Oracle
Switching to the Oracle XE driver instead of the Microsoft for Oracle driver fixed the issue. I've tested all the pages and it works fine. Looks like the Microsoft 32 bit driver will not be useful any longer with the TLS 1.2
The scenario is as follow:
Connection from Windows Server 2003 to SQL Server 2005 works smoothly. Now a new Windows 2012 server which hosts the same .net web application unable to connect to the same SQL Server database, it fails with the following error:
A connection was successfully established with the server, but then an error occurred during the login process. (provider: SSL Provider,error: 0 - An existing connection was forcibly closed by the remote host.)]
As it is working fine from Windows 2003, I guess the issue could be one of these:
Backward compatibility issue, as the new box is Windows 2012 instead of Windows 2003.
Network connectivity issue. However I can confirm the network path is fine as I can telnet port 1433 from the web server to the database server and also part of the error message is
A connection was successfully established with the server
Any help would be appreciated.
You need to install this hotfix for Windows Server 2003. It adds TLS_RSA_WITH_AES_128_CBC_SHA AES128-SHA and TLS_RSA_WITH_AES_256_CBC_SHA AES256-SHA cipher suites to Windows Server 2003.
Without these 2 cipher suites added to Windows Server 2003, anything from Windows Server 2008 R2 and above, will not be able to create an SSL connection to Windows Server 2003. This includes SQL Server connections, and any other connections that rely on SSL.
Why? Because Windows Server 2008 R2 and above, have no ciphers that match with what Windows Server 2003 has (the old ciphers have all been removed from new OS's for security reasons); therefore Windows Server 2003 drops the connection because there's no matching cipher available.
Microsoft Hotfix for Windows Server 2003: https://support.microsoft.com/en-us/help/948963
You need to check your SSL and TLS settings(the server only allows 1.2 and your client only supports 1.0.)
Check the following kb page for more inforamtion
TLS 1.2 support for Microsoft SQL Server
I had a very similar error message:
Microsoft ODBC Driver {Version number here} for SQL Server : SSL Provider: An existing
connection was forcibly closed by the remote host.
I found this guide and this post to be very helpful on this issue. One suggestion was to "upgrade your ODBC driver", tried that and it didn't work, most of the other discussion is around "Checking you SSL settings" in some shape or form.
What I did to resolve my issue was enable TLS 1.0, 1.1 and 1.2 on my SQL Server (in my case 2019) and then on my client systems enable ONLY TLS 1.0 and 1.1 (explicitly disabling TLS 1.2) using the toolset linked here. This seems to have resolved my issue.
Recently a classic ASP app that interfaces with SQL and Oracle was migrated from windows server 2003 (IIS6) to IIS 8.5 windows server 2012R2. Users are inconsistently getting an error when a connection opens up to Oracle, but not for SQL.
Microsoft OLE DB Provider for ODBC Drivers error '80004005'
[Microsoft][ODBC Driver Manager] Driver's SQLAllocHandle on SQL_HANDLE_ENV failed
*This is being thrown on 'cn.open' below
Set cn = server.CreateObject("ADODB.Connection")

The server is using Oracle11g 64 bit driver with default ODBC settings. Fetch buffer size 64000, LOBs enabled, cache buffer size, with failover enabled (10/10). Each time it is reported by a user by the time I get to their desk or try it myself I can't reproduce. 98% of the time it works without issue. Any help or suggestions would be appreciated, I feel this has to be a configuration problem but I can't seem to gain any ground on this and it doesn't help that I can't reproduce it.
Under IIS Manager, go to
Application Pools --> [YOUR APP NAME] --> Advanced Settings
Enable 32-bit Applications --> Select TRUE
Load User Profile --> Select TRUE
It was worked for me, hope helps for you also..
I have a Windows Server 2008 R2 that serves services on IIS7. I enabled TLS 1.2 as you see below
But unfortunately, on of my client is said that they got SSL connection error using TLS 1.2. When I tried to check using OpenSSL, really there is a problem with TLS 1.2.
So, could you please help me, how can I fix this issue?
From Technet
For TLS 1.2 to be enabled and negotiated on servers that run Windows
Server 2008 R2, you MUST create the "DisabledByDefault" entry in the
appropriate subkey (Client, Server) and set it to "0". The entry will
not be seen in the registry and it is set to "1" by default.
I have a ASP site which is working fine on Windows Server 2003 & IIS 6.0.
I migrated to Windows Server 2012 R2 IIS 8.5
I am getting an error when it tries to connect to a database:
Provider cannot be found. It may not be properly installed
Error Details:

My connection string is as below:
GetConnectionString = "Provider=SQLNCLI.1;Data Source=" & m_DALServer & _
";User Id=user;Password=pwd;Connect Timeout=3;"
I have checked the ODBC Data Source Administrator (32 bit) on new server(2012) and found below two related drivers
SQL Native Client 2005.90.4035.00 Microsoft Corporation SQLNCLI.DLL
SQL Server 6.03.9600.163.84 Microsoft Corporation SQLSRV32.DLL
I have enabled my app pool to 32 bit and Managed Pipeline to Classic.
Some drivers where installed by Tech Support Team. Which drivers I am not sure. But because of the patches I saw SQL Server Native Client 10 available in ODBC sources and my issue was resolved without any code change.
If any one having same problem kindly check if the correct drivers are installed on the server. You can also verify by going to ODBC Sources(32 bit) and check if the SQL Server Native Client 10 is available.
Thanks all for your time.
Try SQLCNCLI and SQLOLEDB as your data provider.
These are both OLEDB drivers, rather than ODBC.
Here's a list of the connection strings for each version of SQL from http://www.connectionstrings.com/sql-server/:
SQLNCLI - for SQL Server 2005
SQLNCLI10 - for SQL Server 2008
SQLNCLI11 - for SQL Server 2012
