Windows Server 2012 R2 - iSCSI Storage Virtual Disk Error
Greetings!
I'm working on adding a new iSCSI Virtual Disk on a Windows Server 2012 R2 server and I'm running in to an error while running the "New iSCSI Virtual Disk Wizard". The error occurs on the "Create iSCSI virtual disk" step and is as-follows...
"The WS-Management service cannot process the request. The WMI service or the WMI provider returned an unknown error:HResult 0x80070964"
This is a server I've added Virtual Disks too before, but I'm wondering if this is just some bizarre WMI issue. Any thoughts? Thanks in advance!

TightVNC (Virtual Network Computing) portable version, what does it save to system registry?
TightVNC portable version can be run off a USB but it says this; " Please note that this application DOES save some settings to the system registry. However, the application is a self contained executable and can be launched directly from a portable device on any Windows PC.:
My question is; What does it save to the system registry of the host computer?

Disk Space Monitoring
Hi r/sysadmin,
I'm in need of a way to intelligently monitor disk space. The issue is, there are a couple thousand servers to monitor disk space on, and the disks can range anywhere from 128GB to 4TB. Defining thresholds per disk, per server is unmanageable. Anyone have any ideas?
Edit: Environment consists of Windows and Linux.
Thanks,
Scott

Read only network share, with modify folder
Hi guys, I've got a question.
I have a network share \\share\documents that has word templates.
The problem is, people accidentally save their modified files over them.
I tried to make a symbolic link \\share\documents\modify pointing to \\share\documents
The idea was that modify folder shows the same content, but has r / w permissions, wile documents folder only has r permissions.
It seems that the permissions for symbolic links don't work when shared.
Do you have any ideas how this could be accomplished?
Restricting the write permissions won't work because too many people modify the templates regularly.
I could also share the folder twice, but I would like to avoid making another share. We already have quite many.
My shares are managed with DFS on server 2012 R2.
## Edit:
Here is what I tried to make the link:
Administrator command prompt:
mklink /D "\\share\documents\modify" "\\share\documents"
The link works when I access it with my personal administrator account on the server, but I cannot open it with any clients.
Error is "The symbolic link cannot be followed because its type is disabled".
Permissions are correct and I even tried to change the folder owner.
## Edit2:
Well would you look at that. Some Google and I got the link working.
Unfortunately I still cannot have different permissions for the same folder, so I am still looking for a solution.

File Management Scenario, How To Approach
I'm looking for some thoughts on a file management issue in my environment.
We have a team which is generating more and more data every month. In the past year, they've filled up the 2TB volume on a single file server I deployed for them. They're showing a rapid growth, and have data retention requirements for 6 years. Providing the actual space they require isn't the problem. It's managing the space I'm worried about. Naturally, I don't want to keep just adding 1TB every few months and winding up with a 20TB monster in a few years.
I'm considering setting up a Hyper-V virtual file server cluster(Windows 2016), with deduplicated ReFS volumes. I would give them multiple smaller volumes, and the illusion of a singular folder structure with DFS. This would allow us to break up the existing volume a bit and plan for growth. I would be able to add more volumes if needed, and give them high availability for maintenance.
I've had good luck with ReFS and its deduplication in my home lab and in lower-scale production scenarios. Though I've never used it for a full-scale production file server. The data I'd be storing isn't a great candidate for deduplication, but since they do a lot of versioning, I should still get some good space savings. I also do ReFS on my CSVs and I'm not sure if I need to worry about deduplicated ReFS VHDX on ReFS CSV; probably not, but ReFS is still kind of new and took a while to gain my confidence.
Anyway, how have you guys handled this type of scenario, and what kind of gotchas have you run into?

AD authentication troubles after a move
OK so, I'm kinda stumped on this one so far. I'm making progress but.. I dont fully understand the problem yet.
We moved offices, we did so by department, so I had to keep everyone working on their original ips and do a bunch of natting between 3 sites. I used a dummy server for DHCP and DNS, repointing the DNS to the natted ip (I suspect this is the problem..)
Everythings just fine until we move offices.
After moving offices, we're getting auth errors on the exchange server that is on site (but not the ones off site) so printers cant scan, not authorized to login, users computers aren't getting GPOs as well for the same reason.
I get an Schannel code 42, which is a "Bad certificate" issue. OK.. so where is this cert and how do i fix it?
I just ran a packet capture and saw 3 machines trying to connect. It's not terribly useful to me but I see this:
LDAP 225 searchRequest(46) "CN=Certificate Templates,CN=Public Key Services,CN=Services,CN=Configuration,DC=bs,DC=totallynotafakedomain,DC=wow" baseObject
and then..
DAP 232 searchResDone(46) operationsError (some stuff here I took out) In order to perform this operation a successful bind must be completed on the connection.
after that the relationship ends. The fire is gone. They go their separate ways, but not before asking about a wpad.domainnamehere.nope which it says doesn't exist. (and it doesnt..)
Is my semi-generic info here of any use to help narrow this down? I'm confident this is a bad cert, PROBABLY from the workstations themselves. But I really can't feasibly drop/rejoin every machine in the domain, and since the exchange server that didn't move separately is acting up with the TLS connections and scanners etc. my thought is that the servers the antisocial one here.
I did some tooling around with certutil trying to narrow it down, looking at the certificates snap in on mmc, nothing sticks out to me. I don't see anything that expired recently. Maybe the cert isn't expired, but has bad data? Can I just.. make it generate a new one?
Any insight is most appreciated!

Performance Monitor Metrics
Hi all,
I'm looking into a few issues in our environment and I intend on using Performance Monitor on the suspected culprit servers.
Can you advise me what are the best metrics to use when investigating virtual server performance issues? (IE CPU, RAM and I/O).

Windows Server 2016 - Remoteapps SSO, certificate authority not trusted
Hey guys,
I'm in the process of building a remoteapp collection and everything is working great sofar - except 1 thing: Single Sign on or Passthrough, howevery you want to call it, isn't working.
I want my users to click the remoteapp icons and then it just opens. But when I'm testing it, a yellow window appears that says something á la:
"The certificate does not originate from a trusted certification authority."
I check my RDS-Connection brokers but both of them are using a validated certificate:

Any veamm people here?
I've been tasked with getting a solution for backing up some workstations running various systems on site (50 WS). I have some experience using veamm with virtual servers and liked how it worked. I've looked at veamm workstation agent and it seems to have everything we would need. Only thing is do I need veamm server too? Or is there another way to manage multiple agents on separate systems? Thanks

Syncing shared calendars and mailboxes to mobile devices
We are an MSP and host our own exchange email system for our clients. We used to be able to use the OWA app for shared calendars and folders without any issues. Now that it has been deprecated, we are at a loss as to how to regain the functionality. Our previous clients hadn’t complained about it when it went away, so I didn’t learn until a week ago that it had been removed when a new client was requesting their calendar be added to multiple phones. The Outlook app only supports o365 shared calendars and mailboxes, so that leaves us in a bind (thanks Microsoft....) Any alternative apps that sync with shared calendars?

Known Folder Move, Documents folder fails
Hello.
I work for a municipality where the kindergartens have their own computer, and as we are moving most of our clients over to intune I am looking to use KFM for the folders as they save way to much on a local disk. Such as picutures of the kids etc.
But when I am testing the KFM via OMA-URI's in intune it seems to fail at the Documents folder. The error message I get is following;
"Internal video in Documents seems to be a symlink or catalog...." - Have anyone experienced this error?

Unexpected O365 Credentials Prompt
Afternoon all. Has anyone else had a pop-up box appear asking for creds in O365?
It claims to be from https://autologon.microsoftazuread-sso.com and is asking for username and password.
I've not been able to find anything on google (my google-fu may be still hungover though).
Anyone else?
[Edit] The prompts appears immediately after I sign in (with MFA), then vanishes after 10 seconds.
