After migrating to Windows 10 Build 1809 from Build 1607, setting up sessions with the same socket IP and Port not working.


There is a PC with Windows 10 Build 1809 with a listening port 105. A client connects to this port with a certain IP and local Port. Then performs a SYN - PSH - FIN sequence. Then if it tries to set up a session some mili seconds later with the same socket IP and port the communication seems to be blocked. right part of the Wireshark image. With Windows 10 Build 1607 the second comunication can be established see left side of image. Wireshark indicates "TCP Port numbers reused" .


It was tried deactivating Firewall in case the new SYN telegram is dropoup, change timeouts via "HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters" registry keys.


The session can be established again AFTER 60 seconds!!.


So far I read, here is no porblem with setting up sessions with the same ip addresses and ports, t. But... firewalls, loadbalancers, ids systems and other systems that do something active with the traffic might keep state information. Even for a little while after the session has been terminated.


Any idea which Service or system in Windows 10 Build 1809 is causing this problem?

Event Viewer problem with latest Windows Build 1607

After installing the new Windows build 1607, the Event Viewer stopped recording events under Diagnostic Performance. (Before 1607 I checked the files located under Windows.old dated 9/23/2016 and located this file which indeed did have a list of events
recorded.)

Since the initial 1607 download there have been two new builds automatically installed on my laptop.



The last step in an automatic download is the RESTART. Prior to my rebooting, I checked the Diagnostic Performance and for sure, these had the list of events.



Rebooting by me, causes the Diagnostic Performance errors to disappear.

As suggested earlier I have run the SFC/DISM commands with no errors reported.

Any Ideas?

My Windows 10 version keeps showing me as version 1607, Build 14393.1593

Hi,

Since you mentioned that your computer is on Version 1607, it's not set to receive updates for Version 1703, Creators Update. Additionally, Windows 10 Build 16257 is an Insider build that only those who joined the Insider Program will receive. If you are
interested in the Insider Program, we suggest checking this
article by our MVP Andre Da Costa that contains steps for installing Insider Builds. If you want to upgrade to Creators Update and not the Insider Build, follow the steps listed

here.

Note: Before making any changes to your computer, create a backup of your files to prevent data loss.
