We currently have 5 servers, all with Windows 2003:
1 x Windows 2003 Standard edition as a network load balancing machine and also acts as the PDC
2 x Windows 2003 Standard edition as web servers which are load balanced by the above
2 x Windows 2003 Enterprise edition as SQL boxes. Both are attached to a shared storage array
I successfully set up the managed, load balanced machine as the PDC and also set up DNS successfully (I think - I have heard that this is the main cause of domain connection issues).
All machines are connected to a HP 2425 switch, with private connections between the load balancing machine and 2 web servers through a second switch (HP 2325) for the purpose of load balancing. The 2 SQL boxes are also connected to each other directly for the heartbeat.
I managed to add both the web boxes to the domain with no problem, but both of the SQL boxes are having problems. When the domain name is entered, it returns an error that a domain with the name specified could not be found. I have triple checked TCP/IP settings on both boxes, both connections and also verified that the switch/cables are working OK. I have also checked that the PDC has its DNS server address as its own
I am at a loss here and the problem is, I need to get this fixed today at some point. I'm sure there is something I have missed or maybe an Enterprise server cannot connect to a domain which has the PDC as a Standard edition?
