I have two W2K Standard servers on 1 domain. Primary DC is also running Exchange 2000 Standard. The name of the Primary is xx_yy1.domain.com.
I have recently received an email that states
“Please note that underscores are invalid characters in hostnames (see RFC 952 and RFC 1123). Since many sites will now reject email from that machine, I would advise changing the hostname.”
Since this is the primary, and also running Exchange, how can I change the name to something like xx-yy1.domain.com?
