Win10 1803 Upwards, DA SMB File Upload failure (Kemp LBs) RRS feed

  • Question

  • Hi All,

    Got a stupid issue with DA, support has not been great, so I'm throwing it out here to see if anyone has a clue.

    Below are the results of a few days testing. Basically since 1803 I cant get a decent connection, I personally think it is related to the IP HTTPS adapter update in 1803. (It was changed from "IPHTTPS Adapter" to "Microsoft IP-HTTPS Platform")

    Tried changing the Windows Auto tuning for TCP Receive window, it made some difference, but not to the issues at hand.

    So one one hand I get upload failure, on the other I get horrific downloads. Can't seem to win.

    Other things that have been tried are..

    Primary Site Router Changed from Cisco ASA 5515-X to Meraki MX-250   (No Change)

    Virtual Loadmasters Setup & Tested  (No Change)

    Client Side routers, tested different brands.   (No Change)

    Tested in different countries  (No Change)

    Removed AV from Clients & Servers  (No Change)

    Kemp LM in Transparent mode  (No Change)

    Kemp LM with DSR   (No Change)

    Change Windows Rwin Auto Tuning   (No Change)

    Change MTU On Clients  (No Change)

    Change MTU on Kemp LM   (No Change)

    Servers are virtual running on Hyper V 2012 R2 cluster, on Dell PowerEdge R820's

    1703 support ends October the 8th so I'm on a time limit too, how do I always find the awkward issues lol.

    Any insights appreciated.

    Paul.
