Hi folks,
We’ve been having an ongoing issue for a while now in that some PCs and laptops (Win 7) in our company can’t be contacted by hostname i.e. if we try and RDP from one Windows 7 PC to another the RDP session fails as if the PC isn’t turned on, but it is indeed turned on and connected to the network.
Even if we ping the host name of a particular computer that is on it fails to reply but if I go into DHCP I can find the hostname bit it has a different IP address assigned to it other than what is listed in DNS for that host name.
So for some reason when some computers get switched on and be allocated a new dynamic IP address through DHCP the corresponding record in DNS doesn’t seem to get updated meaning we need to go into DNS and manually amend the Host A record with the new IP address that it has been given so we can RDP onto that computer using the hostname.
At present aging and scavenging isn’t enabled in our environment as we are afraid to in case it removes live DNS entries that just haven’t been turned on in a wee while. Does aging and scavenging just ignore static DNS entires and does aging and scavenging work in DHCP as well?
One other thing I noticed is that if I delete an incorrect DNS Host A record and create it manually and assign the hostname and the correct IP address it says static rather than having a timestamp on it. When I create the new record I always click on our domain in the Forward Lookup Zone and on creation I always select Create the associated pointer (PTR) record so not sure why the manual record doesn’t get a time stand.
So any help/advice or suggestions would be greatly appreciated.
Thanks,
Bonemister
