We have about 1 or 2 cases a day where our helpdesk is unable to remote control one of PCs. This is due to there not being a DNS record for the PC they are trying to remote control. If I run a "ipconfig /registerdns" from the PC in question, a DNS record gets created and all is well. When I check our DHCP logs, there are several of the following errors:
31,03/14/11,12:56:49,DNS Update Failed,192.168.144.129,PCNAME.ourdomain.com,-1,
In the DNS tab of the properties of our DHCP server, I have the following selected:
-Enable DNS dynamic updates according to the settings below:
Always dynamically update DNS A and PTR records (radio button selected)
Discard A and PTR records when lease is deleted (checkbox checked)
Any reason why a "ipconfig /registerdns" would work but the normal DHCP process would not?
