Basically I have an issue with the DHCP that is issued to the users whom I support. When a user turns on the machine each morning, they are getting the DNS address settings of the old domain which the server used to belong to. Its really bizarre because everything else is fine.
I have checked the DHCP from the server in the site and it is completely switched off. We give out DHCP from a central data centre in the US...
If I do an IPCONFIG /RENEW from a command prompt on the machines that are affected - the right settings do come across. If the user reboots their PC/Laptop, the problem then restarts again.
This is affecting their MS Office Communicator which is where the problems are happening.
Any ideas or suggestions would be greatly received.
