I am using an SQL Server 2000 db. I have a VPN concentrator that a few users
use to access the system from home. Everything used to work, now it doesn't.
They can get into the LAN using their usercode/password combination. They can
get to Outlook for email. It takes a very long time to connect, but it does.
I can copy files from drives mapped to the server. However, anything having
to do with ODBC returns an error. Even if I try to set up a new ODBC
connection from the remote client, I get the error. The clients run TCP/IP.
This is the error:

connection failed: SQL State 'HYT00' SQL Server error: 0
[Microsoft][ODBC SQL ServerDriver] timeout expired

Any ideas as to what may have happened? The server is set to auto update.
Could a patch have caused this problem?
