TCP Window Size

Hello,

        I am tuning our server and clients.  I upped the window size in
the dsm.sys and dsm.opt to 2048 from 32, but I get errors in the actlog.
I guess I am looking for the correct syntax.

Client dsm.sys entry
TCPWindowsize       2048

Server dsmserv.opt entry
TCPWindowsize   2048

The error messages are below, any ides.
