I was messing arround with services on my laptop and after that I could connect to remote database server. Message that I received is telling me that remote machine actively refuse connection what is look like firewall but other WS could establish connection with no problem.
If I try Communication Diagnostics with IBExpert TCP/IP test with port 3050 is succesfull but connection to database is not. Same message on every server I tried.

Where did I go wrong with service that made my laptop unusable for Firebird?

Yes, one more clue, the only program what could make connection is "Sinatica Monitor for Firebird". That program could connect to any server I tried and all others could not.
