They had to restore everything from backup and reseed the databases to get email flowing again. I think they have a ticket in with VMware to try and figure out what the hell they did that could have caused such a problem.

Eh, I think FERPA's almost (is?) as big of a deal as HIPAA, and physical access control is almost nonexistent there, so I don't know if I can disagree with them. Then again I fully admit to being way under-qualified to make a logical judgment one way or the other. In any case, I learned something new. Just kinda assumed white-listing would be done at most medium/large businesses/environments.

Before my time, I know they evaluated it for a wider CMS/DAM but the cost was too high at the time. I would certainly look at the paid version of it for that size of deployment. For what we use it for, it is robust and does not gives us problems. I know they are a big player in the field and echo the 'stay the gently caress away from Sharepoint' mantra.

Misogynist posted:IP reservations by MAC are common, but it's also common to leave a small free-range space in the DHCP scope to do initial configuration, assuming that the techs will use the web UI from the computer they're setting up. Really, it depends what works best for your org's workflow, though. Where I work we're about to install packetfence on basically every switch in the company. So far the tests have not gone great, with the one guy who is administering all of it frequently yelling things like "it's not supposed to do that!" or "I already told that what to do why isn't it listening" or having servers or registers randomly fall off of the network. I'm looking forward to the full deployment which I'm guessing will happen within the next month, because if it hasn't worked at 4 stores, what could a hundred more possibly hurt?

This makes no sense at all and there is almost certainly more to the story than VCenter crashed because the C: drive filled. VCenter doesn't interact with any of that stuff beyond pushing configuration changes to the hosts, and if it disappears then things will just happily continue running indefinitely.

I'm long past being surprised at what that sector gets up to. I really like it on a small scale. I use whitelisting at a shop I do the IT for, since I don't mind helping my brother out. Small enough that whenever a new change comes through I can just go in, grab the device, whitelist it and go home (its on my way home anyway). I did this because someone kept breaking into the Wifi, I assume they were being given the password. Since the whitelist, no issues.

I'm just telling you what the 1st shift team lead told us about the previous day. Everything was down for over 4 hours while they scrambled to put poo poo right, and he just wanted to let us know the day after in case there were any aftershocks. If I were a betting man I would wager that our new Virtualization guy did something that started a chain of events that brought the entire infrastructure to its knees, but because he's the only person who has complete access and control over it could say whatever the hell he wanted and no one would be able to gainsay him without a detailed examination by someone with equal access and superior skill. Since there isn't anyone at our location who does, the point is moot.

Got a request to deploy some Modbus SCADA signatures to our sensors. I tried calling several departments that manage physical/industrial security to see if they have any machinery or systems that utilize it on their PLCs/ICMs, but none of them know. I think this points to one of the bigger problems with industrial security, which is that the people generally in charge of maintaining these types of systems usually have no idea about the technical underpinnings.

I recently advertised a position which I was unable to fill due to it being in the middle of nowhere and no one with any experience applied. It is either already re-advertised or just about to go out again... But anyway, I had an internal candidate who didn't have any experience in IT apply - he has decided to email HR and demand an explanation as management encouraged him to apply as he is a respected member of staff who often helps colleagues with IT issues (etc etc etc) I don't know the guy personally so I had to go from his CV - interestingly his email to HR had more detail about his IT experience than his CV which is why he was unsuccessful. Should be an interesting chat when I give him feedback. Alas... I just want an assistant

I recently started work on a new remote desktop (terminal) server for a client. I wanted to remove the default Server Manager and Powershell icons that are automatically pinned to the taskbar for users. I created a GPO to do this and removed security permissions to these shortcuts via the built-in local Users group. I updated the policy on the terminal server and the icons are still showing up. Hmmm, odd seeing as I was testing this using a domain user. I went to double check the permissions on the files and verified only Administrators can access them. Naturally I go to check the permissions of the Administrators group, looks normal. Domain admins are administrators and a couple other users which administer the domain. Hmmm... *opens up Domain Admins group* "Domain Users" I tested further and confirmed I could access administrative shares on DCs and obviously anything else I want. I immediately brought this up to my boss and he immediately went Let's cross our fingers and hope someone doesn't get CryptoLocker.

This seems like the most appropriate of the IT threads to ask this. It seems that the Radiology director is getting a bit overwhelmed with doing his normal day to day stuff as well as being the 'PACS Admin'. I feel like my current position is pretty much a dead end, so I'm quite interested in this possible upcoming position and he knows that I'm quite capable as a PC/Server and sometimes network tech. However, I don't know much about PACS. So, I know there's more than a few other fellow healthcare IT folks here. Whats the best way to start learning PACS? More specifically, McKesson PACS (Recently upgraded to v. 12). I'm definitely going to be searching around on this when I get home, but I thought I'd ask here as well.

Yeah, I'll definitely talk to him and let him know I'm interested in the position. The other hurdle I just found out about is that he's also wanting the PACS admin to be a Rad tech as well. Here again, I certainly wouldn't mind learning that but, again that's going to take some time to learn.

Misogynist posted:I missed this earlier, but I'm putting an actual $20 up that someone misconfigured isolation response on the HA cluster and the isolation response was what took down vCenter in the first place. I actually have administrative access to vCenter, whereas everyone else in the Messaging team is restricted to VMUser. Apparently it was just too hard to give me VMUser access, so the project lead overseeing Virtualization just went ahead and gave it to me. I commented that I wouldn't do anything bad in vCenter like delete a VM from disk, and he just gave me a pained expression. It's actually been pretty useful having that access because there's been a few times when a DAG cluster would suddenly go down and no one would have the first clue on 3rd Shift what was happening. I usually sit over by myself since I'm weekend 3rd shift (you know - the lowest of the low) and that's when one of them remembered that for a time I actually monitored and maintained the virtual infrastructure's physical components and could at least log in to vCenter. drat, I really need to get my VCP5 now. Maybe there's going to be a job opening soon.

Goons, help settle a useless argument with my IT-employed friends: Datacenter vs Computer Room vs Server Room. Which one is right? When do you use each? Generally I consider a room full of systems, dasd, etc to be a computer room, while the building these rooms are in is the datacenter. But most of the time when I call a computer room a computer room, I get laughed at for sounding antiquated. Opinions?
