The first thing I would do is revalidate the IPv6 configuration on the web server, starting from the network interface, down to the web service configuration. I would also try the ipv6only=on statement in the nginx config file, and see whether that makes a difference.

Hi,
I migrated a web application from a local (virtual) server running Windows Server 2003 to another local (virtual) server running Windows Server 2012 R2.
In our warehouse we do order picking with (non domain joined) pda's using this web application. The (motorola) pda's run Windows CE, and are connected to the network over wifi / wlan.
I can connect to the web application on the old server from the pda's, but I cannot connect to the web application on the new server. I cannot even connect to the default website on the new server.
I can connect to the web application on both the old and new servers, with normal domain joined PC's running Windows 7 and 10, and also with my iphone (safari browser).
So the question is, how do I get my pda's to connect to the web application on the new server?
Google has not been forthcoming, or I simply haven't been able to figure out the right search term.
Any help very much appreciated. Please let me know if I have left out pertinent information or if there might be a better forum for this question.
Regards,
Johan

First off, are we sure it's not a network issue like firewall or routing? Can the PDA see the new web server. You may not have something like ping on the PDA, but you should be able to ping or traceroute from the server to the PDA.
Assuming its not one of the above, could it be a SSL/TLS issue? Does the WS2012 server listen only for https, while the PDA is trying http only? If the PDA is trying https, does it speak a compatible version with the server (e.g PDA is using SSLv2 while server only accepts TLSv1.2 and later)? If that all seems correct, are there any logs on the WS2012 system that show the PDA connect attempts and why they were rejected?
Keep Calm and Carry On

Thanks for your reply. I wonder if it was some sort of dns / cache / whatever issue, as I got it to work this morning by simply using the IP address (which didn't work either yesterday afternoon).

Hello all. I wanted to repost this with some more info that will hopefully help understand my question a little better. Please see screenshots links a the bottom of post.
Our email program needs to connect and send mail using MS O365 accounts and the TLS protocol for security reasons with port 587. For testing, I used TELNET to the O365 STMP server using port 587, the EHLO command and starting TLS using the STARTTLS command but that is far as I can get. After that, anything I do just sits there and no more responses from the server. I am trying to figure login commands at this point, which I researched from Google but didn't seem to work, much less anything else. A set of connection rules I found about TLS here on Code Project is the list below. If I need to, I can send a screenshot of what the TELNET session looks like to help out. Any help would be very appreciated. Thanks!
1. The client connects to the server using TCP.
2. The server sends a welcome message using the un-encrypted connection to the client.
3. The client sends a EHLO command using the un-encrypted connection to the server.
4. The server responds to the EHLO command using the un-encrypted connection.
5. The client sends a STARTTLS command using the un-encrypted connection to the server.
6. The server responds to the STARTTLS command using the un-encrypted connection.
7. The client negotiates an encrypted connection with the server.
8. The client sends a EHLO command using the encrypted connection to the server.
9. The server responds to the EHLO command using the encrypted connection.
A) This first image is how I TELNET to email server for testing purposes. In the program, we use SMTP sockets to do the same thing: Image 3
B) This next one is a normal SMTP screen using port 25 (NO TLS) and connects successfully: Image 1
C) Last screenshot is my TELNET attempt to TLS protocol in which I am stuck on what to do next after successfully starting the TLS sever: Image 4

If you are going to be running this from your main office or even several offices/places that have a Static IP or FQDN that uses Dynamic DNS, why not add a Receive Connector to your Office 365 Portal.
Login to Office 365 Portal[^] with your Admin Credentials -
Click Admin -> Admin centers -> Exchange -> mail flow -> connectors.
Click + (New) -> From: Partner organization To: Office 365 -> Next -> Name: Bruce (what ever) -> Next -> Use the sender's IP address -> Next -> + (Add IP) 1.2.3.4 -> OK -> Next -> Select Security restrictions and click your way through.
You should be able to side step TLS and still be somewhat secured through the connector.

Hi
We have using Essl K20 BioMetric System.
And device is connected Using TCP LAN and maintain data in Access DB, The Data transfer more difficult from device.
Each Time we download from etimetrack Desktop App.
And now we need to transfer data automatically to PC with out manual download.
Any possible way for this?

You're going to need to check the documentation on the device API to find out if that's possible.
I would suggest that you also contact the manufacturer; they may have different firmware builds that do what you want, even if it's not normally possible with the mass-production build.

Our DHCP servers are in dire need of the names of the Scopes to be updated with a new "naming convention".
I've exported the entire thing as XML (via PS).
If I edit the Scope names, can I import the newly edited XML to change nothing but the names? Everything else is remaining the same.
Or will it balk and say the Scope already exists (I assume it checks via the ScopeID) and do nothing?
Yes, I could probably just delete everything, and import the whole kitnkaboodle, but I'm wondering if just a name update is possible.
EDIT: In case anyone ever needs to know, importing scopes will NOT just update existing scopes. It will skip them as already existing, and just add any new ones.

Due to peer pressure and lack of time.. I installed "hide.me" VPN on my machine... break the networking..
Then I unsinstalled it...
Now every second time I reboot I got no network... can't even contact my router on 192.168.0.1...
I check all the adapter properties, everything is on autodetect...
What could be wrong? Any idea?! :'(
I might have limited my router to accept only some MAC address... but wy would it work every second time?! 
I googled Hide.me. They seem legit.. Dunno why it didn't wok on my pc...

Have a look at the services running.
There may still be a proxy DNS running that was not removed when you removed hide.me(not a piece of software I am familiar with).
Also do you have Acrylic running on your machine? If so this also uses a proxy DNS which can cause issues.

This sometimes works:
Open a CMD prompt as administrator
At the prompt type this:
netsh winsock reset
You'll need to restart after this.

We have a numbered directory for every project, set up automatically when the project is accepted. There is a standard subdirectory tree.
I am constantly finding project directories missing and eventually find them under another directory - someone has carelessly dragged and dropped them. I'm trying to find a solution to stop them (short of committing a major crime).
So far I have thought of changing permissions on the project directory so that only the Administrator can move them, and then changing permissions on all subdirectories so that they are not inherited but Everyone has RW rights.
This will be complicated to do, as staff must, on occasions, be able to create special purpose subdirectories and they will default to inheriting the folder properties.
Is there a better way to lock down directories but allow access to everything below them?

This is where you need to be using some sort of version control software/system.
By using version control, your directory structure and contents will be versioned which means that it will be easy to trace and restore when anything changes or moves.
I have seen others struggle with the same issue you are describing and they never came to a solution, however as soon as I started working in tightly version controlled environments what you describe was no longer an issue.
You could create one main repository or a repository for each second level directory - the only downside is that it will take a bit to educate people and set it up but it will allow you control and transparency over actions taken of individual files.

How many project directories are we talking about? Are these on a Windows Server?
Make each Project Directory a share that is mapped as a separate drive for each user, that will stop the top level directories bsing moved.
Subdirectories can still be faarrrkkkked, but you can use Share/NTFS permissions to limit what users can screw up.

The high-mucky-mucks want people to provide a PIN when printing. Binging (I don't like Googling) shows me how to do it on the desktop on a per-job basis, but we have like 400 printers in the network and they want every one of them to require the user to enter a pin at the printer before the job prints.
Semi-easy, right? But they don't want the user to set up a PIN for each job, they want them to have to use their SmartCard at the printer to kick off the job, i.e. it doesn't start until they are physically at the printer. (Basically, they'd have to "log in" via AD for the job to print.)
Is this possible to configure at the Print Server? Or will we have to configure each printer to require it (like it already does for scanning)?

Usually you make an inventory of what is possible, instead of making it up and checking if it is at all feasible.
