Hi, had a scenario today whereby I was unable to telnet in to a SQL server on port 1433 to test the connection from the client PC.

However the application could connect and this alone verifies it is working  on port 1433 for sql.

My question is how can a telnet command on a specific port be blocked ??

This scenario is across domain, across firewalls and WAN to remote site.

Can the firewall block this?

Or can group policy pushed down to clients block it even though i could run telnet then open a connection and it would attempt to connect and subsequently fail - what Im getting at is that group policy would more than liekly prevent telnet form executing intially?!

thanks
Nathan
