I do not get any connection to my MS SQL server!
If the mssql extension was loaded in the php.ini, sometimes it comes to access problems when only TCP/IP is used. You can fix that problem with a newer "ntwdblib.dll" from Microsoft. Please replace the older file in the \xampp\apache\bin directory with your newer file from Microsoft. Apache restart. Thank you Horst for this topic note!
I cannot find the ntwdblib.dll. Microsoft says it is not available as they are stopping this type of support.
Is there another fix or another source for the dll?
