[BUG] ODBC based apps cannot connect to SAPDB

Hi,

it's me again with the old nice sweet litte bug that's internally called
with the short name "ODBC driver reports error '709 connection refused'
although the ODBC driver can establish a TCP/IP-connection and get's a
'rejected bad connect packet' message from the server that you can
easily see if you're using ettercap".

I'm a little but ironic, since i reported the Bug twice already and now
i have the following situation here at home:
- a Linux Server with MaxDB 7.5.0.8
- a Windows XP Laptop with SQLStudio 7.5.0.5
- a Windows XP Desktop with SQLStudio 7.5.0.5
- a Linux Server with SAPDB 7.4.x.x

The Desktop PC is a fresh installation of WinXP. This installation
hasn't seen any SAPDB/MaxDB Software before i installed SQLStudio.

If i use the Desktop PC to connect to the MaxDB 7.5 Server, than i get
the famous "error 709" and if i use the Laptop, everything works!

Both computers can connect to the SAPDB 7.4 Server.

I'd like the following to be done:
- Fix the stupid error message reported by the ODBC driver since
"connection refused" lets everybody think of the TCP/IP-error instead of
a "rejected bad connect packet" from the server
- Bring some light into the darkness how this can happen, that two
installations of the same software can behave that different
- Figure out why the ODBC-driver doesn't want to connect to the MaxDB
Server since the error now occures with both ODBC-driver installations:
the SQLSTUDIO-specific installation the the general standalone installation.

I wish i had a real bugtracking-system like Bugzilla or something, since
i don't want to tell the whole story over and over again.

Thx
   Sven
