Hi there, we have one wesite which is built using php, the website is trying to connect to a database on another server which uses SQL 2008, when trying to connect we get the following error message.

The login packet used to open the connection is structurally invalid; the connection has been closed. Please contact the vendor of the client library. [CLIENT: ***.**.**.**]

We have done some research and found the following.

http://www.microsoft.com/technet/support/ee/transform.aspx?ProdName=SQL%20Server&ProdVer=10.0&EvtID=17832&EvtSrc=MSSQLServer&LCID=1033

MaxTokenSize 20000

The recomendation has been followed with no change in the result.

This is the local error message that we have been receiving.

Warning: mssql_connect() [function.mssql-connect]: Unable to connect to server: remote..................com:.... in /home/............/public_html/sql/index.php on line 8
Couldn't connect to SQL Server on remote......................com:.....

Can anyone suggest where to go from here?
