The following error shows when browsing the OSCE server web console:

Your OfficeScan session has timed out. Please log in again.

The issue still persists even after doing the following:

1. Access the OSCE web console using the other machines of the network.
2. Verify the OfficeScan virtual directory permissions on IIS (e.g. Allow anonymous is enabled).
3. Debug the OSCE server. The following line shows repeatedly:

   03/12 11:58:38 0ae4-0ae0 (4) [cgiShare:ShowSetCookeHeader] CreateFile "C:\Program Files\Trend\PCCSRV\\TEMP\.key_8862" FAILED! - cgiShare.cpp(2673)

4. Increase the management console timeout using the steps in this KB article.
5. Go to IIS manager > Properties > Directory Security > Anonymous Access and Authentication control > Edit.
6. Check if IUSR_<Server Name> is enabled.
7. For IIS7.0 or Later (OSCE XG):
   1. Open IIS Manager and navigate to the level you want to manage.
   2. In Features view, double-click Authentication.
   3. On the Authentication page, select Anonymous Authentication.
   4. In the Actions pane, click Edit to set the security principal under which anonymous users will connect to the site.
