Port 1434 Filtered

External Since: Mar 04, 2004 Posts: 4

Using PortQryV2 I got the result that on a remote server port 1434 is
FILTERED.
How can I change its state to LISTENING?

Thanks, Dan

Hi Dan,
The response should show that it is Listening
It may be failing to enumerate the instances, so it is returning back as
Filtered.

Try running -n Servername -o 1433,1434 -p both -l logfileName.txt

Sample:
UDP port 1434 (ms-sql-m service): LISTENING or FILTERED

Sending SQL Server query to UDP port 1434...

Server's response:

ServerName xxxxxxx
InstanceName MSSQLSERVER
IsClustered No
Version 9.00.0981
tcp 1433
np \\xxxxx\pipe\sql\query

4Z

==== End of SQL Server query response ====

UDP port 1434 is LISTENING

Thanks,
