Hi, I have PHP Version 5.0.5 in my machine and a script that connects to two external MSSQL servers... SERVER1 = SQL SERVER STANDARD EDITION, WINDOWS NT 5.2 (3790) SERVER2 = SQL SERVER DEVELOPER EDITION, WINDOWS NT 5.1 (2600) Both are setup for a user with SQL Authentication, but with SERVER2 I have no problem and with SERVER1 i get: Code: [code]Warning: mssql_connect() [function.mssql-connect]: message: Login failed for user 'sa'. Reason: Not associated with a trusted SQL Server connection. (severity 14)[/code] Is there a compatibility issue?? That error is suposed to be permission for 'sa' problem, but both SQL servers have the sa user with the same password, both with SQL Authentification.......one works the other dosen't....... trying that connection to that server with ASP works ok.......... any idea????? Thanks
