Dear Gustavo,
Please check the version of your Server and SDK is the same. If its the same, is your server and SDK in the same domain?
If not, are you using a VPN Connection to connect to your domain?
If not of the above, is your SMP Server exposed to a public IP?
try to ping SYBASE_SERVER_FLORIDA from command prompt and check with the IP address rather than the name,
If all the above is working, try restarting the server services and try to connect
Hope this helps,
Regards,
Rakshit Doshi
