We run W2003 which was implemented about a year ago. Recently we began to
notice duplicate entries in the forward lookup zone so we decided to enable
scavenging and it appeared to clean up many old records. But we also noticed
that after scavenging, user PC's are not registering in DNS, they are not
creating Host A records and DHCP is not creating pointer records (this is
set in the DHCP scope). This became a problem when users working from home
would VPN to the office and then RDP to their PC using the PC name and it
would not resolve. As a work around I manually created Host & ptr records
for their workstations. No error messages are created on the PC's or the
servers, the DNS entries are just not being created.
Here are 2 other errors that are in event viewer, the top one is on the
secondary server and the lower one is on the primary:
