rebuilding a Subscriber - Invalid Host name

[Scott Hanson]

All,

Rebuilding a  Subscriber in a 8.6(2) cluster.  The publisher Host name has an underscore in it.  For the Subscriber rebuild, I am on the First Node Access Configuration screen and it is telling me only Alpha Numeric characters and hyphens are allowed.  How in hades do I add this subscriber to the cluster when the install process tells me underscores are not allowed?  Not really trying to rename all the severs.

Thanks.

That is a DNS restriction that should have been observed during the installation of your servers, not sure how you managed to install it.

While a hostname may not contain other characters, such as the underscore character (_), other DNS names may contain the underscore.^[4
