Block Port 1433 On Windows 2000 Server
Jul 20, 2005
Hi
I have a question regarding the SQL Server(SQL Server 7) port 1433.
Some body is trying to hack into our Windows 2000 server through port
1433. Is there a way i can close this port? I tried using a tool
called Ipsecpol.exe ( Internet Protocol Security Policies Tool). But
when we run netstat, it still looks like they are able to connect to
the server using port 1433. Has anyone come across this problem? I
would appreciate it very much if somebody could send in any
suggestions regarding this.
Thanks,
Ann

I've got SQL 2000 set up on a cluster running Windows 2000 Advanced Server (w/SP1).
Setup for Failover Clustering appeared to succeed normally on both nodes.
The SQL 2000 server logs show:
2001-01-11 10:02:57.82 server SuperSocket Info: Bind failed on TCP port 1433.
2001-01-11 10:02:57.85 server SQL server listening on Shared Memory, Named Pipes.
2001-01-11 10:02:57.85 server SQL Server is ready for client connections
I've checked to see if something else is using port 1433 (unlikely) and don't see anything.
The physical node that SQL 2000 is currently on has no other cluster resources assigned to it.
Any ideas?

I want to know how to check whether SQL Server 2000 can listen to port 1433 or not. If I run netstat -a, am I suppose to see port 1433 regardless of what service pack I have applied to SQL Server 2000?

SQL Server 2012 two node single instance cluster.
For DB access from application severs, do we need to open port (1433) for NODE IPs too ?
Or is it enough if we open the port 1433 only for VIRTUAL IP ?

I'm working on a completely virgin install of SQL Server 2k in Windows 2003.
Just after install I check that the TCP/IP protocol is enabled under the
server properties and then I try to Telnet into port 1433. On this one
particular box I get back the following:
C:>telnet localhost 1433
Connecting to localhost...Could not open connection to the host, on port
1433: Connect failed.
For comparison I tested telnet on a couple other machines and I get back a
blank window ready for my commands, as I'd expect.
I've checked the firewall settings and other IP Filtering settings to see if
any of those were blocking traffic to 1433... nothing. I've triple checked
the SQL Server settings for any "problems" and nothing jumps out at me.

Ok,
The Scenario is as follows:
24/7 Production Call Centre server running NT4.0 and SQL 6.5 with all the latest service packs.
SQL mail fails(with dull regularity) and the SQL server services stop.
When the SQL server Services are restarted an error message appears stating that Port 1433 is in use after which nobody can connect via TCP/IP. Obviously the port believes the previous SQL session is still running, and won't release the port to the "New Application requesting it".
On a unix system you can force a port reset so you don't need to shutdown and restart the box. Can you do this from either SQL or NT?
Any solutions would be greatly appreciated the DBA's are 100 Miles from the Servers, so restarts are reliant on other people!

Does anyone have an idea on why when using IP with port 1433 that on the SQL 2000 Server a bind failure happens on port 1433 and are not able to get to the SQL using IP but you can use Named Pipes.
Would greatly appreciate any help.

Did a search on port 1433 but nothing came up in the search.
This question is more geared to DBAs more then SQL developers.
I have a SQL 2000 server on a win2k3 machine. For some reason it will not listen in on TCP port 1433.
Shared memory and Named Pipes do though.
I checked the Server Network Utility and I see TCP/IP listed right under Named Pipes and I see that the default port is 1433.
Any ideas how to get SQL to listen on that port?

Been having SQL Server 2000 running for some time now, but recently it stopped listening on TCP port 1433, the log reports its listening on shared memory, Named pipes and Rpc, but no sign of 127.0.0.1 port 1433 or any errors to say why it won't listen.
I've done a netstat -na and nothing else is listening on that port, tried restarting using the enterprise manager, gonna try restarting the entire Server when everyone has gone home, but I'm pretty sure its been restarted recently.
All the other archive logs going back a few days show its not listening.
Yes, I have used the Server network utility to make sure TCP/IP is enabled and set to 1433, even added a comma and 1434 to see if it will listen on multiple ports, no go.
Any help?

Hi,
Does SQL mobile require port 1433 to be open for RDA? I was under the impression that all synching occured through port 80. But when 1433 is restricted a connection cannot be completed.
I may be missing something really simple. My understanding of tcp/ip networking concepts are not very solid.
Thanks,
Tony.

Version: SQL SERVER 2012 enterprise edition and SP2.
Due to one of the security reason, I have changed default port 1433 to another port number in configuration manger tools->protocols for MSSQLSERVER->TCP/IP --> IP ALL section mention another port number.
After restarted service, SQL SSMS able to connect server itself and new port number also LISTENING.
But SQL client SSMS not connected to one of the PC side after changing default port.

Hi. I'm a SQL Server novice, so apologies if any of this sounds simple.I am running Windows XP SP2, and have just installed SQLServer 2000. Ineed another application to connect to SQLServer, and am specifying itto do so via localhost:1433, but keep getting an error whenever I trydoing so saying it cannot connect to the database. A colleague of minehas the exact same set up on his machine, and he can connect to SQLServer fine. Running 'netstat -a' at the command line on his machinereveals that the system is listening to port 1433/ms-sql-s. Runningnetstat on my machine shows that the system is not listening to1433/ms-sql-ms. I have checked in Network Config in SQLServerEnterprise Manager, and TCP/IP is set to be using 1433.To confirm this, my application can connect over the network to mycolleague's SQL Server. but he cannot connect over the network to mine.So I'm pretty sure the issue is related to this 1433/ms-sql-s problem.Does anyone know how to resolve this? Many thanks.

We have 2 clustered SQL instances (2 physical servers in each cluster). Instance2 needs to be setup as a linked server on Instance1.
At this time port 1433 between them is not open. I am referring to the port on the network switch, not in the Windows Firewall (ports in Windows Firewall are already open).
Is opening the port between virtual IP-s sufficient? Or does port need to be open between all physical source/destination IP-s as well?

Hi,
I have SQL Server 2000 installed on my Windows XP (SP2) machine. I have the port set to 1433 (under Server Network Utility-->General-->TCP/IP). Here's the problem: when i run
netstat -anb
nothing is running on port 1433. What i DO have is this:
TCP 0.0.0.0:1036 0.0.0.0:0 LISTENING
[sqlservr.exe]
Before I rebooted my computer it was running on port 1032. Anyone have any idea why this is happening? Thanks.

Leon writes "I am trying to connect to a W2K3 Server's 2005 Reporting Server through my laptop's (WXP Pro SP2) SQL Server Management Studio.
I turned Port 1433 on in the server's Windows Firewall and was able to connect to the server's database engine from my laptop, but I have to turn Windows Firewall on the server off completely to be able to connect to the Reporting Server.
I have tried all the ports listed for SQL Server in the Microsoft documentation (TCP and UDP), but they seem to have no effect.
Can anyone tell me which port or ports I need to turn on in the server's firewall so that I can access Reporting Services through my laptop's SSMS?
Thanks in advance.

Hi,
Just upgraded some development desktops to Vista Business. However we need
to still connect to some older remote windows 2000/SQL 2000 servers.
Trying to setup an ODBC system DSN on our Vista Business local desktop we get the
following errors -
-START ERROR WINDOW-
Connection Failed:
SQLState: '01000'
SQL Server Error: 772
[Microsoft][ODBC SQL Server Driver][TCP/IP Sockets]ConnectionOpen
(SECDoClientHandshake()0.
Connection failed:
SQLState: '08001'
SQL Server Error: 18
[Microsoft][ODBC SQL Server Driver][TCP/IP Sockets]SSL Security Error
-END ERROR WINDOW-
Any help greatly appreciated as this is stopping us from making
database/table connections etc. We've checked the firewall setup and all is well there.
PS - we can still connect fine using XP or windows 2000 desktops and their
local DSNs.

I've just started getting this EXCEPTION_ACCESS_VIOLATION (0xc0000005) on machines using Windows 2000 sp4 connecting to SQLServer. This is crashing JVMs (multiple Sun versions and BEA also) in the Java VM frame (outside our code). This has just started recently - perhaps with the last set of patches? Has anyone else seen this or know what I could do to get more information? Could this be related to updates to named pipes?
Thanks!

We have a SQL Server 7.0 system in NT 4.0 environment. We upgraded our users to Access 2000 and started to work with this. Now we installed a new
server which is Windows 2000 based and the domain is different from
the SQL servers domain. We then installed Access 2000 on Windows 2000
to use with terminal server. But I noticed that there was a problem
with the program. I then looked at the program which was written on Access 2000 and saw that the tables and views can't be seen. The program runs but
I can't see the views and tables. Another thing is access disconects from SQL Server when I want to see the tables. So what can be the problem.
In one part there is an Access 2000 on Windows 2000 server. On the other part SQL Server 7.0 on Windows NT 4.0. And Access can't see the tables in SQL server.
