SQL Fehler ???

[Lena1979]

Wawi hat immer gut funktioniert, auf einmal beim Neustart schreibt er mir Netzwerkfehler mit folgendem Log:

AW: SQL Fehler ???

Hallo,

der Fehler ist:

A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)

Die Wawi kann den SQL-Server DataSource=XXX/JTLWAWI nicht mehr finden.

Bitte prüfen:

1. Unter Globale Einstellungen -> SQL - Servername - ist da korrekter SQL-Servername drin
2. Firewall prüfen ob diese evtl. blockiert
