My remote server running 08 R2 can connect to it's SQLExpress instance via SSMS. db Properties has 'Permit remote connections ticked'. Firewall off doesn't help. Another thread here shows 'sqlcmd -e -s ip\instance' as a suggestion - i'm not familiar with that way in - only use SSMS - but if that's _supposed to work locally, it's not in my case.
What's the next step to implementing remote access? Is the 64 bit coming into play? 64 bit version is installed but the configuration manager has a couple nodes with reference to '(32-bit)'
