After a restart of the server where Columbus is installed, some Columbus services do not work correctly anymore. The Columbus Management Console (CMC) may crash and the Firebird log would contain the following error many times:
INET/inet_error: connect errno = 10061


This problem does occur if Windows actively refuses a connection to the FireBird database port 3050.


To reserve this port for the communication with the Firebird database server the port entry "gds_db 3050/tcp" has to be added to the SERVICES file on computers, where the console, the infrastructure services or the client are running. You will find the services file under %windir%\system32\drivers\etc.
Make sure that the DB server and all other Infrastructure Servers have the entry for port 3050 in their services file.

Note: Some Exchange services block the use of port 3050 even if one reserves this port in the services file. Therefore it is not recommended to install Columbus on the same server as MS Exchange is installed.
