Figure 1

This seems to occur on Windows 2008 R2 servers with NFA 9.1.x. Where the problem is caused by IIS 6.0 with the ASP setting "Enable Parent Paths" parameter being set to False by default. In IIS 5.0, the ASP parameter is set to Enabled by default.

NOTE: This only needs to be done on the NPC server and NFA master console if these are distributed…

  2. Access the Internet Information Services (IIS) Manager from the administrative tools
