Connect to MS SQL server using Windows Authentization

[Culprit_CZ]

Hi,
I need your help,
How can I connect to MS SQL database using Windows Authentization?
To access Web page I need to have rights from WIN NT.
And I want connect to server trought AUTH_USER.

When I use

$Conn = MSSQL_Connect($MyServerName)

I become a error that login failed for user "\".

[TTT]

should work like:

odbc_connect("$dns","$uid","$pwd");

I want use only

$Conn = MSSQL_Connect($MySQLServer)

no additionals parameters
No UserName and password
