Hi, Actual config
1 - Primary 2012 SP1 CU1 2 - Secondary 2012 15 - DP's We currently have a secondary site that has a "link has failed" status, looking at the rcmctrl.log on the secondary site I have the following error ERROR: Exception message: [Login failed for user 'NT AUTHORITY\ANONYMOUS LOGON'.~~OLE DB provider "SQLNCLI11" for linked server "xxx.xxx.com" returned message "Invalid connection string attribute".] Last week we changed the default 1433 port to 2032 and had the firewall modification applied, everything was working and then this morning we had this error. I have been trying to find a solution but I'm out of ideas! Thanks
