Problem : The Captools/net Server Control Panel displays an error in the Virtual directories item with "/CTWebScripts"... "Error - Access Denied 401". Captools/net Desktop and the web programs do not run due to this error.

This means that the IIS is unable to authorize the user. Solutions to try :

1.) Check if Anonymous authentication is allowed or not in IIS.

a.) Go to IIS Manager (Server Control Panel | Utilities | Open IIS Manager).

b.) Under the Web Sites item, right click on "Default Web Site" item and click on "Properties".

c.) On the "Directory Security" tab, click on the "Edit" button to display Authentication Methods.

d.) Make sure that the "Anonymous Access" check box is CHECKED and the User Name is "IUSR_XXXX".

e.) Go back to Server Control Panel and Reset IIS and click on Refresh to test.

2.) Check if the "IUSR_XXXX" user account is enabled.

a.) Open Windows Control Panel | Administrative Tools and Computer Management.

b.) Under the "Local Users and Groups", click on the "Users" item.

c.) Make sure that the "IUSR_XXXX" user account is enabled.

d.) If it has a red stop button besides it then it is disabled. Right click it and click properties.

e.) Uncheck the "account is disabled" check box if it is checked.

f.) Repeat this process with the "IWAM_XXXX" user account as well.

g.) Go back to Server Control Panel and click on Refresh to test.

3) It may be necessary to add "Network Systems" as a user under the "Properties/Security" tab for the "Client", "Webscripts" and "WU" folders under the Captoolsnet folder.  Network Systems will need run rights.
