Getting error "Authentication over SSL encrypted channel with the configuration storage server couldnot be verified. To apply the configuration to ISA server computers, a certificate named ISAserver4.contoso.com must be installed on the configuration storage server"
You might see this error when you enable ssl authentication in the CSS tab of the array properties to enable ssl authentication. And in this case CSS name is "ISAserver4.contoso.com" and the server authentication certificate used on the CSS server is issued to "Isaserver4". So we need to use certificate which is issued to ISAserver4.contoso.com.
After using certificate which is issued to "ISAserver4.contoso.com" it shall work fine.
