Customize

ServerInstance string

Specifies the name of the target computer including the instance name, e.g. MyServer\Instance

ServerCredential pscredential

Mode string

Specifies the authentication mode that will be configured: Normal, Integrated, or Mixed

AutomaticallyAcceptUntrustedCertificates switch

Off

Indicates that this cmdlet automatically accepts untrusted certificates

ForceServiceRestart switch

Off

Indicates that this cmdlet forces the SQL Server service to restart, if necessary, without prompting the user

ManagementPublicPort int

Specifies the public management port on the target computer

NoServiceRestart switch

Off

Indicates that this cmdlet prevents a restart of the SQL Server service without prompting the user

RetryTimeout int

Specifies the time period to retry the command on the target sever

ConnectionTimeout int

Specifies the time period to retry the command on the target server
