The following pop-up message may appear when you install or upgrade the OSCE agent on a Windows Server 2008 platform:

"The IIS service on this computer may not work as expected because of a conflict between the Windows Filtering Platform and the OfficeScan firewall. Please restart the IIS service to avoid encountering this problem."
The OSCE agent displays this pop-up message to inform users about the conflict between OSCE's network driver (TMTDI.sys) and IIS 7.0. All websites hosted by IIS will not work when this occurs.
To prevent this issue, restart the IIS service (World Wide Web Publishing Services).
Previous versions of OSCE clients (version 8.0, 10.0) do not check OS versions, so it will trigger the pop-up message even if the issue doesn't actually occur.
