What are the best practices regarding ScaleArc and internal DNS?
ScaleArc recommends that the internal DNS server be the primary dns server for ScaleArcs use.
You set the DNS server during the initial configuration and it can be updated or changed at any time from the Network Settings page.
There are additional changes that are recommended for ScaleArc for MSSQL implimentations.
1) If you are using Windows Authentication you must create an A record and PTR record for the ScaleArc Server. See Article #155 (Add a Host (A) DNS Record Manually to a Windows DNS Server) for detailed instructions.
2) You should add the search domain to the ScaleArc configuration.
Go to Settings>Network Settings
Add the search domain into the Search Domain Field and click Apply
