All about application delivery

In Hyper-V guests it can happen, that the network gets discoonected for certain operations. There are two hotfixes but from my opinion it is also wise to disable all these special features on the netwrok card. Well for sure this should be done automatically – here is a powershell script that you can use:

$key = dir “REGISTRY::HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E972-E325-11CE-BFC1-08002BE10318}” -ea silentlycontinue
foreach ($Name in $key) {
 $value = get-itemproperty Registry::$name -name *IPChecksumOffloadIPv4 -ea silentlycontinue
 IF ($value) {
  set-itemproperty Registry::$name –Name *IPChecksumOffloadIPv4 –Value 0

 }
 $value = get-itemproperty Registry::$name -name *JumboPacket -ea silentlycontinue
 IF ($value) {
  set-itemproperty Registry::$name –Name *JumboPacket –Value 1514

 }
 $value = get-itemproperty Registry::$name -name *LsoV2IPv4 -ea silentlycontinue
 IF ($value) {
  set-itemproperty Registry::$name –Name *LsoV2IPv4 –Value 0

 }
 $value = get-itemproperty Registry::$name -name *LsoV2IPv6 -ea silentlycontinue
 IF ($value) {
  set-itemproperty Registry::$name –Name *LsoV2IPv6 –Value 0

 }
 $value = get-itemproperty Registry::$name -name *TCPChecksumOffloadIPv4 -ea silentlycontinue
 IF ($value) {
  set-itemproperty Registry::$name –Name *TCPChecksumOffloadIPv4 –Value 0

 }
 $value = get-itemproperty Registry::$name -name *TCPChecksumOffloadIPv6 -ea silentlycontinue
 IF ($value) {
  set-itemproperty Registry::$name –Name *TCPChecksumOffloadIPv6 –Value 0

 IF ($value) {
  set-itemproperty Registry::$name –Name *UDPChecksumOffloadIPv4 –Value 0

 $value = get-itemproperty Registry::$name -name *UDPChecksumOffloadIPv6 -ea silentlycontinue
 IF ($value) {
  set-itemproperty Registry::$name –Name *UDPChecksumOffloadIPv6 –Value 0

 }
