I bit of a head scratcher.
I was replicating to a client's database and all was well. Now I have noticed I am getting the errors:
The process could not connect to Subscriber 'XXXXX'. (Source: MSSQL_REPL, Error number: MSSQL_REPL0)
Named Pipes Provider: Could not open a connection to SQL Server . (Source: MSSQLServer, Error number: 53)
An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (Source: MSSQLServer, Error number: 53)
Login timeout expired (Source: MSSQLServer, Error number: HYT00)
We're replicating across the internet to a client site. I can telnet no problem and from SSMS, I can connect to the database.
The box is set up as publisher and distributor.
