Hi, I got this issue with a Legacy server (Win 2K3) which I would need to use in a new data centre (its actually a sub-PRD + DR site).
I have 2 sites with 2 IP range :
1. HQ : 11.1.1.xxx (subnet 255.255.255.0)
- Domain Controller : 11.1.1.1
- File Server : 11.1.1.2
- Legacy App server : 11.1.1.3
2. Remote Office : 11.1.10.xxx (subnet 255.255.255.0)
- Legacy App server : 11.1.10.3 (IP address to be added after moving)
Proposed workaround (failed) : Install 2nd LAN card to Legacy App server (Legacy App server would have 2 IP : 11.1.1.3 & 11.1.10.3)
Issue : Some applications and reports were hard-coded with server IP address of 11.1.1.3 (should had used host name but that was in past).
- If I have 2 LAN cards on, the Legacy App server cannot ping Domain controller and database fails to start as authentication fails (cannot ping 11.1.1.xxx)
- If I have only 1 LAN card on (11.1.10.3), the Legacy App server and Database can run, but application fails as cannot connect to old IP (cannot find 11.1.1.3)
I am open to all advise and suggestions....Thanks in advance...
