Take the firewall client off the SQL server and make sure the default
gateway of the SQL server is the ISA server, if that is the route to the
internet. Did you make the Server Publishing Rule for the machine?

Hi,

I recently upgrade a WinNT 4 SP6a Proxy server to Win2K SP4 with ISA SP2. I
have to allow remote users to connect to a SQL server 7 SP4 on Winnt 4 SP6a
behind ISA. The IP is static. It was working fine with Proxy but now I have
the following with clients on the Web:

[Microsoft][ODBC SQL Server Driver][TCP/IP Sockets] Network error and if I
try SQL Query Analyzer I have

Unable to connect to server xxx.xxx.xxx.xxx
ODBC:Msg 0, Level 16, State 1
[Microsoft][ODBC SQL Server Driver] Time out error

I have the ISA port 1433 and 1344 (for the apps running with SQL) opened and
listenning . If I run netstat -na on both servers, both show ports as
listenning. I can telnet the ISA external IP on both ports. ISA client is
installed on the SQL server.

I ran thru a similar problem when I configured it for the proxy 2 years ago
and don't remember what was the problem exactly. With the proxy, I had to
add wspclnt.ini in the sql server binn folder to map the port 1433 to the
proxy server and added a connection in SQL server network utility which was
mapped to the external IP of the Proxy. I tried it with and without and
there is no difference. I also remember that I had to use credtool on the
SQL server. Do I have to do it with ISA?

I'm familiar with ISA and i often have to open ports for apps and it works
fine so what is diffenrent for SQL server?

Any help would be greatly appreciated.

Thanks in advance.

Interesting....you shouldn't have to do that but it depends I think if the
SQL server is a Secure NAT client or not.

Yes there is a Server rule. Guess what, by doing it the same way I did it
with the former proxy, it works. I disabled the server publishing rule,
added the wspcfg.ini file in the mssql7\binn folder and it works??? At the
setup time and according to the situations I had with the ISA, I first
thought that it wouldn't work using the same settings as it was with the
proxy server but it appears that is not the case.

Thanks anyway.

Steve
