Two parted question really...
First off, I've been trying to enable my SQL Server 2008 R2 to allow remote access so my friend can view it from his RDBMS (also SQL Server 2008). I've enabled TCP/IP, I've allowed Remote Access/Connection, I've opened TCP and UDP Ports and also added the sqlserver.exe and sqlbrowser.exe as inbound and outbound rule to my firewall and I've started my SQL Browswer server so it's running (all of this is because of tutorials on google on how to enable remote access...). But for the life of me I can't get it to work. I've got the server up and running and it works absolutely fine locally so it's nothing like that...
Secondly, how do I actually test this? Could it be that it actually does work but I'm unable to test it myself and he needs to be the one who tests it? If so, how would he do it. I read somewhere about some connection string but that's doing it with code, right? Once again, I have no trouble logging on/accessing my SQL Server locally regardless of whether or not I'm doing it with code or via a RDBMS.
Hope it wasn't tl/dr; and thanks in advance
