I have an application installed on my app server and it database resides on another server with SQL2000 installed. Not sure if the client was installed on my application server or not. But yesterday someone installed sql7.0 client connectivity on my app server and since than my original app is not able to connect to my app database. I'm getting following error. I tried uninstalling client and installing SQL2000 client still get the same message. Any help will be appreicated.

SQLState: '01000'
SQL Server error: 20
[Microsoft][ODBC SQL Server driver][TCP/IP Sockets]connectionOpen(PreloginHandshake()).
Connection Failed.
SQLState:'08001'
SQL Server Error: 20
[Microsoft][ODBC SQL Server driver][TCP/IP Sockets]Encrytion not supported on SQL Server.

What can I check to see what went wrong.

Thanks,

Jay

I would install the latest MDAC. You could also install SQL 2000 service pack 3a on the client machine.

I would guess that encryption has been set on in the client network utility.

Cursors are useful if you don't know sql.
DTS can be used in a similar way.

It looks like someone turned on Encryption in the client...

run C:\WINDOWS\system32\cliconfg.exe

make sure the Force protocol encryption is disabled (unchecked)
