Re: PHP & MSSQL on Linux

See what perplexes me is that the extension seems to be installed (I
uninstalled the php-mssql rpm and got an error that the extension
wasn't installed).  Reinstalling the rpm returned me to my original
error that the connection failed. As I mentioned TCPDUMP tells me that
there is no traffic going to my database server.  The website where I
got the php-mssql and freetds RPMs told me that I wouldn't need to
recompile PHP but other sites tell me that I need to configure php with
freetds.  

Since I'm running on a linux box, the solution to your problem doesn't
apply to me.

Thanks for your continued help,
Robbert
