My VDS was upgraded from a Name Based to an IP Based. Now, nslookup command on my domain returns two IPs
The DNS zone file of the VDS has now 2 A records (one to the new IP and one to the old IP).
The bug is that the settings of the DNS servers do not work properly if there are more than 2 name servers. (DD name servers)
In order to fix it, you will need to manually edit the DNS record file (c:\winnt\system32\dns\):
IN NS ns1.nameserver1. ;1
IN A 18.104.22.168 ;2 <- OLD IP
IN A 22.214.171.124 ;3 <- NEW IP
IN MX 10 mailserver1 ;4
Remove the line with the old IP.
*This is a known Bug in SD 3.6, and UP2 will fix it.
