I'm getting this event about twice an hour on average on the computer attempted being logged into, MemberServer09
by computer account MemberServer22. Logon type 3 indicates File/Print sharing -or- IIS type access. MemberServer22 serves no purpose right now but has IIS installed for a symantec site. I disabled the APP Pool on server 22 for those sites in IIS Console without effect. I just also re-enabled those, then stopped IIS Server via console and stopped services via n
et stop WAS && net stop w3svc
successfully, awaiting results. Both servers running 2012 R2.
MemberServer09 is a domain controller, the events 4625 are logged here. see below. Anyone know how to prevent these from coming up?
