I have a Windows 2003 AD domain that I just installed ADWS in. The install went well and after server restart, ADWS starts up fine. I get the normal events that is has started and that is is servicing the Directory instance: GC and Directory instance: LDAP. Looks good at this point. I try opening powershell and importing the AD module which fails because it can't find a server running ADWS.
There is an event on all 4 of my domain controllers like the one below after startup. Also get this event when stopping ADWS.
Event Type: Error
Event Source: ADWS
Event Category: ADWS Startup Events
Event ID: 1005
