Harry:

I've been using a Windows build for FreeTDS for about a year now.
When I built this under Windows Vista using VC9, I recall there was a bug in 
the <net.c> source  file which failed to activated the Winsock dll.
(Windows has that annoying TCP/IP initialization protocol. ugh!) This might 
be the cause the " login failure" you observed.

The way I found this issue was to build a debug version of FreeTDS, and 
construct a simple "hello SQL" app to drive the library.
As I recall, the bug was fixed in a subsequent patch, but I never got the 
chance to test the patch.

For the first step in the process, can you see if you can get a simple VC10 
"hello SQL" app working?

That'll be great, because this is really frustrating for me.

When I only had dblib.lib I was getting linker errors about some tds_ 
functions.
