SAS Web Server does not start on Microsoft Windows when its configuration files refer to Universal Naming Convention (UNC) paths


With the update to Apache 2.4.63 delivered in the SAS® 9.4M8 (TS1M8) Hot Fix M1V006, SAS Web Server 9.47 does not start when its configuration files refer to UNC paths. 

This issue also occurs in SAS® 9.4M9 (TS1M9) on SAS Web Server 9.52.

Workaround

To work around this issue, add the following code to httpd.conf above UNC paths:

<IfModule core_module>
    UNCList <remote host>
</IfModule>

Here is an example:

<IfModule core_module>
    UNCList rdcxxx20020
</IfModule>

You can add this workaround before or after you apply Hot Fix M1V006. 

The workaround also resolves the issue in SAS 9.4M9.
