#9461 - DNS configuration issues 

Some DNS records fail to update and appear in DNS in a timely fashion. Some users will be joined to the PBR network but will have no record in DNS. In some cases, a DNS record will only appear on one site DC or just one DC and not replicate across. I have not noticed this issue since Matts departure but there may be issues like this around the railway that I have not noticed.
