Issue
When trying to map a server the following error is displayed.
Error 20011
Resource Not Available
Reason /Possible Case
Symantec Endpoint Security or Symantec Enterprise Protection 5.x has an option called Stealth Mode Web Browsing if this option is enabled it can cause the error above.
Note: This option may be enabled due to an automatic update pushed down by Symantec.
Solution
In Symantec software, disable Stealth Mode Web Browsing.
Note: This setting is typically found under Policies Firewall | Protection and Stealth | Stealth Enable section. Remove the checkmark from the checkbox next to Stealth Mode Web Browsing.
Note: Please refer to the Symantec website at _http://www.symantec.com to obtain the most current information. If necessary, contact the vendor directly for additional information.
