We have moved Production Server from 5.x(18.104.22.168) Network to 58.x(22.214.171.124) network, also we have moved it from one Domain to another Domain. Since then we are facing multiple issues and errors in starting services.It was like looking at the worst print ad ever: I sat there staring at the description with my patented WTF face, knowing there was something terribly wrong, but needing a few seconds for it to sink in.
Inspite of giving all logon privileges to the dependency user for $YourBigApp services, it is still its not starting. We are also getting errors whenever I am login as "RPC LOCATOR encountered a problem Pls tell microsoft about the problem". I have tried to re-configure services but it is giving errors like "unable locate SERVER HOST". We are getting Similar erros at app servers end also.
Their IP address was 5-dot-something? That can't be right. This is an Indian company; all the low numbers are entire Class A IP blocks owned by the original ARPAnet participants like IBM, AT&T, DoD and Xerox. The 5-block is IANA's. I did a quick look-up and found out that the 58.2.x.x B-block is owned by some Indian ISP. Pinging these two different addresses told me everything else I needed to know. IANA wasn't using the 5.x IPs; the ISP was. Yeah, that would explain the RPC errors, the inability of every machine to to get an address and contact each other except via NetBEUI, all of it.
Resolved in about 20 seconds: fix domains, meet my friend NAT, fix routing, use your own damned IPs, Root Cause: 17-Fuckwit. I went to call the idiots and take ownership of the ticket but another monkey had beaten me to it. I'd waited to enter my ID to take the thing but held off to make sure it wouldn't blow up in my face, turn into a stinker, or possibly be handled by one of the corporate contacts who've managed to make the shitlist, people such as $BigBank's MookMan.
And just as I finished writing this, who should happen to submit a ticket? None other than the notorious MookMan himself. The room exploded with the howls of monkeys of different nationalities all trying to do their best Pacino/DeNiro Brooklyn: "Iss da mook! It's fockin' MookMan!"
One day a real rain is gonna come and wash the scum and the filth outta da server rooms.
