Hi Ralph: Please find attached to this email a zip file of script t.cmd. Copy the t.cmd to Windows server and collect some traces for me
1. open cmd with admin permissions (Run as administrator)
2. start network trace
3. execute the following command
>t.cmd srvon
4. reproduce the scenario (I would like all three scenarios)
5. One done reproducing, execute
>t.cmd srvoff
6. stop and save network capture
7. zip all t.cmd outputs and networks captures and upload to the following link
