A number of Windows2003 server have recently restarted after windows updates and the IAS service fails to start. The event log states that a port is already in use. By modifying the IAS server to support only 1812 and 1813 (removing 1645,1646) the service starts.
Has anybody else experienced this? Is it related to a new Windows Update?
The servers all run McAfee VirusScan 8.5 patch 5 also.
