Configuring Automatic Upgrades
Note
If the server supplies MS-DOS style directory listings, the sensor cannot parse the directory listing and
does not know that there is a new update available.
To change Microsoft IIS to use UNIX-style directory listings, follow these steps:
Step 1
Choose Start > Program Files > Administrative Tools
.
Step 2
Click the
Home Directory
tab.
Step 3
Click the
UNIX directory listings style
radio button.
