Unable to connect to Self Service Portal (SSP)

Error When connecting to the SSP there may be errors such as ‘Syntax Error’ or ‘Object Unexpected.’ This may manifest as a popup with a script error, or you may simply see a small yellow warning icon in the lower left hand pane of the browser. In any event, VMs cannot be accessed through the SSP.

Resolution
This issue can be caused by javascript being incorrectly sent to the IE clients due to NIC driver settings on the webserver (the one running IIS for SSP). Disable network optimization settings on the webserver NIC to get things working again.

Settings to disable on IIS server NIC(s)

  • Disable ‘Large Send Offload IPv4’ per one of the articles listed below. Reboot.
  • If simply disabling ‘Large Send Offload IPv4’ does not work, follow the full list of instructions in Article 2.
