I came across this problem and needed some advice on where to look.
I’ve configured a new server for a client, a windows 2003 SR2. The client only has three workstations therefore I did not set up a domain.
The Qwest Actiontec DSL router is handeling the DHCP and DNS functions.
With that being said, when I assign a static IP to the server after about 5-8 hours the server will lose communications with the rest of the workstations in addition I can not send out a email notification via Backup Exec using the SMTP function within Backup Exec (using an external ISP for the SMTP).
However if I use a dynamic IP address assigned by the router all my problems go away. I’ve double and trippled check the IP address, subnet, DNS servers, etc. The problems only happen with a static IP…
Any suggestions?
