This is where a great deal of random firefighting comes from. Lack of workstation imaging tools and Applications are loaded manually - Often indicates a lack of consistent processes in general. If you tell me it's to obfuscate the purpose of your servers to increase security, then you are not going to inspire me with confidence in your skills and knowledge. Random server names - It's not so much a red flag in and of itself, but the reason behind it and what it sometimes indicates. Lack of a ticketing system - Even if you are a one man show, email sucks for tracking issues. Red flags that I might be walking into an SMB/SME IT shit show. BTW, I don't consider these to be advanced rockstar skills, this is really basic shit. Take this with a grain of salt because I've gotten gold and been down voted to hell for this before. I fixed in a few hours what they had been working on for 1 1/2 weeks. Jeez, and once I eliminate all the duplicate MACs, like magic all the dropped packets are gone.Īnd now, of course, work thinks I'm again Scotty from Star Trek. Who does that? why? do they not understand how networking works at all? and my jaw drops.ĥ different MACs have been duplicated. Then I run a powershell script and look for duplicate MACs. How the hell does that happen? Pings are 2 way communications, so if it works one way, it should work the other. Server 1 can ping server 2, but server 2 gets 20% packet loss going to server 1. Start running ping tests all over the place. So of course, I start checking the easy stuff right.įrame size mismatch, IP address conflicts, checking even logs looking for errors, etc. So apparently this problem had been going on for about 1 1/2 weeks. It was one of those days where you walk in the door and someone says, "Oh thank god you are here." before I even put down my laptop bag. So most of the day today, I got to spin my wheels trying to figure out why we were getting intermittent network issues between a group of servers.
