hi,

my server which is running AD, DNS, DHCP and RAS (for VPN) has 2 (A)
records.

*.*.*.78 (LAN)
*.*.*.83 (internal)

when pc's on the LAN side resolve this, they are being directed to the
internal address, rather than the proper LAN address.

can i set priority, as in MX type etc, or is there another way i can make
the LAN IP the proper record?

thanks

neil

This is a good example, we don't recommended to enable RRAS on DC with DNS. This troubleshooting may help,

Neil:

When you have multiple A records for the same hostname in DNS, they
will resolve round robin until it is cached by the client. You should
use a different hostname if you want particular computers to resolve a
specific address. Example:

compname-lan ---> *.*.*.78
compname-int ---> *.*.*.83

Hope that helps.
