When accessing the WFBS console or configuring the Messaging Security Agent (MSA) component, the following error occurs:

The above error appears, because of an incorrect path that was set on the ISAPI filters of OfficeScan or SMEX website in IIS.
To resolve this:
  1. Open IIS Manager.
  2. Select which site you want to configure
    • For WFBS Console: Expand Sites > OfficeScan.
    • For MSA Console: Expand Sites > SMEX Web Site.
  3. In the middle pane, select ISAPI Filters.
  4. Expand the columns as required and look for an Executable path with "\\".
  5. Click Edit:
    From the above screenshot, change the "\\" to "\". The path will be:
    C:\Windows\Microsoft.NET\Framework\v4.0.30319\aspnet_filter.dll
  6. Restart the IIS service and access the WFBS or MSA console again.
