Fixing SSO

Windows stores credentials when you login on the network. Sometimes, in particular for laptops, when you change your network password the credentials are not refreshed. This leads SSO to try to log you in with old outdated credentials
To fix this, please follow these steps

Warning: Incorrectly editing the Windows registry may cause other applications to stop functioning correctly

Step 1. Open Windows Registry Editor
To do this press the "start" button, select the run menu, type regedit and press enter

Step 2. Navigate to the following registry key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa

Step 3. Open (Double Click on) disabledomaincreds

Step 4. In the Value Data input box, replace 0 with 1 and then press the OK button
The window is refreshed with value of 1 for disabledomaincreds

Step 5. Close Registry Editor and restart (Reboot) the computer

Now that the computer has been restarted, iViewXT Single Sign On should be working.

Note: To utilize Single Sign On you must work within the RR Donnelley network or be logged into the network through VPN.
