Finding if Service Accounts are in use

Hello,

We are retiring one AD domain to move to another. We are in the process of migrating users and I was appointed the task of finding out if service accounts are still in use on the domain. I was told I could use EventcombMT to search DC logs to try and find out if they are in use and what for. I tried running it by checking the security log for success audit and failure audit, and in the text field I put the service account name. I am getting zero results.

Does anyone have any suggestions on using EventcombMT to find this information? I have no background in scripting so that is not an option. I also only have access to free tools. Any advice would be helpful. Thanks.

First of all service account and user account are same thing. The only difference with service account is, we change few settings. Like Password never expires.

The one option to find which account is working is to check with the application owners, who are using them

Second option is to check the lastlogon stamp.

Now the problem here is normally people configure the application with service account and don't logon for long time. Which again makes it diffcult to tarce them down.

Only way is to do it manually,

First check what are the accounts set with password never expires.
Check with the application team about those account, if they are using it or not
Once you have all above information, you can disable the suspected account and few weeks and see if any issue persist.

All above require manaul work and there is no shortcut to that, as service accounts are configured according to ur requirement

hope this helps

Thanks amitkulshrestha, the lastlogon stamp was one of my first ideas also. However, I was told that the last logon stamp is the last interactive login, not the last use of the account. The guy who assigned this task to me said that accounts used for services and applications don't update the login stamp. So he said I should try to search DC logs and that's where he said to use EventcombMT.

We have 180 service accounts on this list I have. Some of them I can contact the application teams, others, (that don't have much information) I'm stuck trying to search DC logs I guess.

Anyone have any other suggestions by chance, or use how I can use eventcombmt?

Thanks.

If you have a list of host names, i.e. csv, of the servers we could make a script checking.

Also if you have 180 service accounts, you should also have a csv-file for those.

I do have a csv file for the service accounts, but not one for the servers. I'm sure there is one somewhere for it but since I'm new here I'll have to ask around. I have no experience scripting at all or really even running them,will that matter?

Thanks for the offer to build me a script snusgubben. I was not able to get a server list from my manager (security issues), so I just had to use some tools and do the best I could. Thanks though.
